Web Development essentials : Javascript

If you are interested in web development, this is the blog you can ask for. You might wonder why I am starting with javascript without HTML or CSS. The simple reason is if you want to be a web developer, you already know enough about that.

The importance of JavaScript as a web technology can be determined from the fact that it is currently used by 94.5% of all websites. As a client-side programming language, JavaScript helps web developers to make web pages dynamic and interactive by implementing custom client-side scripts. At the same time, the developers can also use cross-platform runtime engines like Node.js (will be covered in another blog)  to write server-side code in JavaScript. They can even combine JavaScript, HTML5 and CSS3 to create web pages that look good across browsers, platforms, and devices. There are also a number of reasons why each modern web developer must know how to leverage all benefits of JavaScript.

Why No Web Developer can Create Modern Web Applications without JavaScript?

Implement Client-Side Scripts

JavaScript was originally designed as a client-side scripting language. A large percentage of websites still use JavaScript as a client-side programming language. The web developers can easily write custom client-side scripts in JavaScript, and integrate the scripts seamlessly into HTML. They can further use JavaScript to make the web pages interactive, respond to users instaneously, and create richer user interfaces, without less server interaction and reduces server load.

Write Server-Side Code

The web developers can also write server-side code in JavaScript by using a cross-platform runtime engine like Node.js. Node.js is designed as a cross-platform and server-side runtime environment. It further executes the JavaScript code efficiently through Google V8 JavaScript engine which is supported by all the browsers this days. The built-in libraries provided by Node.js further allow programmers to run their web applications smoothly without relying on external web servers. Hence, the web developers can use Node.js to write both client-side and server-side code in JavaScript.

Responsive Web Design

Most developers nowadays adopt responsive web design to make a website accessible and look good across multiple browsers, devices and browsers. Responsive web design enables developers to optimize a website for both computers and mobile devices with a single code base. But the developers have to combine CSS3, HTML5 and JavaScript to make the web pages responsive. Hence, the developers must use JavaScript to optimize web pages for mobile devices.

JavaScript comes with lots of Libraries and Frameworks

JavaScript Frameworks and libraries make it easy for web developers to build large, JavaScript-based web applications. There are many dynamic JS frameworks like AngularJS, ReactJS, EmberJS etc. Using these frameworks, developers can easily, quickly, and efficiently develop highly interactive and professional looking web applications. JavaScript also has lots of libraries which you can use as per your requirements. For example, you can do GUI development using widgets like Bootstrap, jQuery or AngularJS.

Easy to Write JavaScript Code without using any Specific Tool

You can write the JavaScript code easily without using any particular type of program or tool. You can just open a notepad and write your JavaScript code. You can use many editors to find out the mistakes in the JavaScript code. The editor reformats the JavaScript code and allows you to discover the bugs and error quickly and easily.

Learn Basics of JavaScript

Learning the basics of JavaScript will help you to understand the required JavaScript skills that are utilized in WordPress development.

Choose the Right JavaScript Framework

You should have basic knowledge of different JavaScript frameworks. Popular JavaScript Frameworks are:(check it out for what purpose they are used)

Angular

ReactJS

Ember.js

• 
• Vue.js

Using JavaScript Framework, you can finish the creation of JavaScript applications quickly. If you are an active WordPress developer then you should have sufficient knowledge of HTML, CSS, and JavaScript. You can use any of the JavaScript frameworks but initially, you should choose React or AngularJS to perform web development work.

The needs of WordPress developers can be divided into two main categories: backend and frontend. If you are into frontend development, you have many options to choose from but if you are a backend developer then you can choose Node.js easily.
