The ongoing Coronavirus pandemic is impacting every part of our lives. Besides, it has wide-ranging ramifications for marketing, advertising and eCommerce as well as several other sectors like travel, entertainment and FMCG. As opposed to, the pandemic has defined a new category of goods called “new essentials.” New essentials are products that help consumers feel
Web development is the fastest-growing industry not only in Bangladesh but also around the world. To grab the dream job in this sector, do you have the skills to stand out from the crowd? On this blog, you can find top 10 basic skills for a web developer. So, Let’s go!
To become a great web developer, you should stay ahead of the curve. You have to learn new technologies and programming languages and focus on the customer’s needs and wants to keep them satisfied. You also have to keep yourself up to date with the industry; thus a better idea is to follow blogs like Sitepoint, Smashing Magazine, Hacker News etc. and of course our blog. To visit at least one conference in the related field each year should be included in your goal.
In web development projects, the deadlines are always just around the corner. So, to stay efficient, it’s vital to manage your time as best as possible. Good developers struggle with it, but some can not maintain their time management skills. I’m sharing some quick, actionable tips so that you can manage your time correctly-
As a web developer, you have to maintain a regular to-do list, and it will help you to do your every task, resulting you can’t skip a job.
Reminder helps you to do a particular task at the right time.
You can follow the 80/20 rule and try to find your daily tasks that eat away too much time without producing enough results. You may be surprised at how much time you’re spending every day doing things that take way too long for what you get out in return.
When you get stuck on a task, don’t waste your time, communicate with your boss or senior to get a better solution.
We know that HTML, CSS and JavaScript are the three fundamental pillars of Web development. HTML (HyperText Markup Language) is a language that communicates with the web browser, and it dictates the structure of each page on the WWW (World Wide Web). It tells the browser how to interpret the data to form elements on a website. We use it to add style on our site, including the layout and design. We also use CSS (Cascading Style Sheet) to properly display in our website on different devices and screen sizes. HTML5 and CSS3 are the latest standards that work in the most common browsers out there.
When you are master in HTML and CSS, in the long run, you’ll want to learn JavaScript. JavaScript is one of the higher-level programming languages, and it prepares websites more interactive and functional. JavaScript will deliver you to create better experiences for users. You can write special features directly onto your sites with JavaScripts.
PHP (earlier called, Personal Home Page) is a server scripting language, and it is a powerful and useful tool for making dynamic and interactive web pages. PHP is a widely-used, free, and efficient alternative to competitors such as Microsoft’s ASP.
Nowadays, many modern consumers use their mobile devices to conduct online searches. Around 60% of online searches occur on mobile devices. So, websites need to adapt to this trend. When websites aren’t consistent with mobile devices, web users don’t display well; users go to a competitive site. That is why a web developer needs to have responsive design knowledge.
Code versioning or version control helps you to track and control, but also revise any changes to your programming. Just imagine that you make a few smaller changes to your code and the whole web site stops working. The changes you made indeed had errors, the quickest and better solution is to track back to the last time of your code that worked.
You can fix any errors or abnormalities in your code by the Debugging process. On average, a developer spends no less than 33 % of his time debugging.
Consumers behaviour is always switching. So, your design, coding as well as development skills will ever express for satisfying the ultimate customers. Therefore, every web developer needs a strong understanding of consumers, especially web consumers, and their need and want. If you can understand them on the whole, it will support you to create the best websites that sell.
In modern-day marketing, Search engine optimization (SEO) is working as the driving force. To get more traffic as well as increase ranking on Google, SEO is the most effective way. Websites that don’t implement SEO won’t show up high enough on search engine result pages. Page upload speed, keyword content, and domain credibility are just some of the SEO skills that web developers should learn.

After a short break, here I am writing the second part of the fundamentals of JavaScript. In this part, we are going to discuss operators, loop, conditions. Let’s get started.
We know many operators from school like “+”, “-”, “/”, “*” those functionalities the same as before.
Let’s note that an assignment = is also an operator. It is listed in the precedence table with the very low priority of 3. That is why when we assign a value to a variable, like x = 2 + 2 + 1, first, calculate the equation, assign a value to x variable.
The remainder operator %, despite its appearance, is not related to percents. The result of a % b is the remainder of the integer division of a by b. For example :
The exponentiation operator ** is a recent addition to the language. For a natural number b, the result of a ** b is multiplied by itself b times. For example :
Increment ++ increases a variable by 1
let counter = 2;
counter++;
alert( counter ) // Value 3;
Decrement — decreases a variable by 1
let counter = 2;
Counter–;
alert( counter ) // Value 1;
The if(…) statement evaluates a condition in parentheses and, if the result is true, executes a block of code.
For example :
In this above example, the condition is a simple equality check (year == 2019). Then the alert year 2019.
The if statement may contain an optional “else” block. It executes when the condition is false.
Sometimes, we’d like to test several variants of a condition. The else if clause lets us do that.
The while loop has the following syntax
While the condition is true the code from the loop body will execute
After every execution of the loop, the value of i will increase by 1, when i become 3, it will not execute code inside while body.
The condition check is executed after the loop executes the first time. A better example of do…while loop is a bank atm machine.
For example:
This form of syntax should be used when we want the body of the loop to execute at least once.
In this blog, we are going to discuss the fundamentals of JavaScript like variables, data types, conditions, looping, and other topics.
The previous blog was about Introduction to JavaScript where we discussed on JavaScript history why it is famous among all web developers, why should we use it in modern web development, and it’s future.
JavaScript codes can be inserted into any part of HTML documents (I hope you have enough knowledge of HTML & CSS) with the help of script tag. For example
Code inside <script> tag automatically executed when the browser renders the page.
<script> tag has few attributes that are rarely used nowdays.
The type attribute : <script type = “text/javascript”>
External Script: If we have a lot of JavaScript code, we can put it into a separate JavaScript file. JavaScript file attach to HTML using <src> attribute.
Most of the time, JavaScript needs to work with information. Consider two scenarios-
Variables which are used to store information.
To create a JavaScript variable, use the let keyword.
The statement below creates (in other words: declares or defines) a variable with the name “message”:
Now we can put some value in message variable using assignment operators =,
var instead of letThe var keyword is almost the same as let. It also declares a variable, but in a slightly different. We will discuss briefly about that topic our next blog.
There are two limitations on variable declaration javascript variable-
Examples of some valid variables name in JavaScript-
Examples of some invalid variables-
Variable named message and Message are two different variables.
Constant variable means unchangeable. To declare constant variable, we use const keyword in JavaScript.
Talking about variables, there’s one more extremely important thing.
A variable name should have clean, obvious meaning, as it describes the data that it stores.
Variable naming is one of the most important and complex skills in programming. So a quick glance at variable names can reveal which code was written by a beginner versus an experienced developer.
A variable in JavaScript can contain any data. A variable can at one moment be a string and at another be a number-
Programming languages that allow such things are called “Dynamically Typed”, meaning that there are data types, but variables are not bound to any of them.
There are seven data types in JavaScript-
The number type represent both integer and floating point number.
There are many operation for number data type, for example multiplication “*” ,division “/” , Addition “+”, substract “-” and so on.
A string in JavaScript must be surrounded by quotes.
In JavaScript, there are three types of quotes-
Double and single quotes are same. Because there is no difference between them in JavaScript.
Back-ticks are “Extended Functionality” quotes. They allow us to embed variables and expressions into a string by wrapping them in ${…},
for example:
The boolean type has only two types- true and false.
This type commonly used to store yes/no value. True means yes and false means no.
Null type just a special value which represents “nothing”, “empty” or “value unknown”.
The code above states that age is unknown or empty for some reason.
The meaning of undefined is “value is not assigned”.
If a variable is declared, but not assigned,its value is undefined:
All other types are called “Primitive” because their values can contain only a single thing. In contrast, objects are used to store collections of data and more complex entities.
The symbol type is used to create unique identifiers for objects.
The type of operator returns the type of the argument. It’s useful when we want to process values of different types differently or just want to do a quick check.
There are two types of syntax :
The call to type of variable returns a string with the type name.
We will discuss more about the Fundamentals of JavaScript like operators, conditions and other things in my next blogs.
Today we are going to start a journey with JavaScript. It is a scripting and programming language that allows you to implement complicated things on a web page like sliders, interactive maps, 2D/3D animation, scrolling videos etc. It can be written in web pages and run automatically when the page loads. Therefore, it does not need special operation or compilation to run. It first appeared in 1995.
JavaScript designed by Brendan Eich and developed by Netscape Communication Corporation, Mozilla Foundation, Ecma International.
When our program is loaded into the memory, it starts execution from the first function call which is foo ()
Hence, the first stack entry is foo (). Since foo function calls bar function, secondly stack entry is a bar (). Since bar function calls baz function, thirdly stack entry is baz(). And finally, baz function calls console.log; fourth stack entry is console.log (‘Hello from baz’).
Until a function returns something, it won’t be popped out from the stack. The stack will pop entries one by one as soon as the entry returns some value, and it will continue pending function executions.
Importance of JS can be determined from one fact that 94.5% of websites use JavaScript. As a client-side programming language, JavaScript helps to make web pages’ dynamic and interactive. At the same time cross-platform runtime engines like Node.js to write server-side code in JavaScript.
JavaScript was designed for the client-side scripting language. Most web developers are still using JavaScript as a client-side scripting language. Web developers can quickly write custom server-side-script and interact with HTML easily. JS can further use to make a more productive user interface without less server interaction and reduce server load.
The web developers can also write server-side code in JavaScript by using a cross-platform runtime engine like Node.js. It further executes the JavaScript code efficiently through the Google V8 JavaScript engine.
Despite being an interpreted programming language, JavaScript simplifies the development of complex web applications by allowing developers to streamline the application’s composition.
Web developers can easily extend the functionality of JavaScript by using several libraries and frameworks. React.js makes it easier for programmers to accomplish specific tasks.
Since its inception in 1995, JavaScript has been growing into the most popular, dominant language of the web. Over the last decade, the adoption of JavaScript has only been growing, showing no signs of slowing down.
The annual survey shows that 69.8% of respondents, as well as 71.5% professional developers, are using JavaScript nowadays according to Stack Overflow. Finally, this is excellent news for developers who either know JS or are planning to learn it.
Our JavaScript Journey will be continue. You can gather a vast idea about those frameworks from my another blog, so keep connected with- Augnitive | Blog
Software development sector is rapidly growing day by day resulting we are getting lots of developers in this area. If there are more contributors, the number of software technologies could increase because everyone wants to make the applications faster, user-friendly and more attractive. Vue JS is one of those software technologies that help the developers cope up with the new trends.
It is a JavaScript framework which is developed by Evan You. It is a progressive framework for building user interfaces.
Integrating Vue JS with a web project is very simple. You do not need the knowledge about JSX, ES6 or build systems. If you know basic HTML, CSS, and JavaScript, you can start working with it. It would be really helpful for a developer for this fast-paced development without prior knowledge.
Flexibility is another good side of this framework. You can just create an app and run it straight from the browser. You can also create a complex application as you need.
The documentation of Vue is very readable and descriptive. There are lots of code examples and these are really easy to understand.
Vue adds and removes classes on components or elements during the transition process. These are 6 different classes which can be customized for handling timing and animation properties.
Just add the Vue Library CDN (you can find it here https://vuejs.org/).
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
There are two ways to build a Vue component, we will see the simplest one here.
Create a new file named app.js and write these codes.
var app = new Vue({
el: '#app',
data: {
name: 'James'
}
})
Create the index.html file and write these codes.
<div id ="app">
Hello <input type="text" value="{{ name }}">
</div>
Add the app.js file after the CDN file in index.html.
And that’s it You have created your first Vue component-based web application.
There are lots of packages which makes life easier for Vue developers. Some of them are,
Vue has made life easier for JavaScript developers. Every framework has some pros and cons. We just need to select our framework depending on the project’s features and requirements.
