JavaScript is a high-level programming and scripting language that enables a web application to be more dynamic.
It is used on the client side for its behaviour with the help of a third-party library (jQuery, Bootstrap and Underscore).
JavaScript is a lightweight programming language that makes it easy to implement and use syntax and semantics that are simple to understand.
It's used on web applications such as Shopping websites, Facebook, Amazon, Twitter, and so many sites.
These sites make use of JavaScript for both their front-end and back-end functionalities.
JavaScript is mainly used for web and mobile development, 2D and 3D Game development, and building of web-server.
Importance of JavaScript?
JavaScript is one of the essential text-based programming languages for building an interactive web application. Some of its functions are listed below;
1. It reduces the repetition of a specific string or variable.
2. With the help of JavaScript, a user can submit a form, which the user can save directly to a database where information is stored and retrieved.
3. You can use JavaScript to make awesome animation for your webpage, with some events like onclick, onmouseover, etc. It reads the function and executes the code within.
4. you can use it to edit, create, and delete text on your HTML page.
5. Styling of the web is included, changing colour size and can implement font.
6. Store valuable values inside variables that you can reuse; with the object and array, you can save multiple variables/strings in a single name.
How to Get Started And Tools to Have
To get started with JavaScript, here are some prerequisites;
1. Brief knowledge of HTML.
2. Brief knowledge of CSS.
It is easy to learn and understand their basic syntax and semantics; to write JavaScript code, a text editor (Notepad, Notepad++) or IDE(Visual Studio, Eclipse, and Atom) is needed.
A text editor is any computer program that enables users to create, change, edit, open, and view plain text files, but the essential developer tools such as Testing Frameworks, Linting Software, Debuggers, and Security Analyzers required to build and test software are omitted.
With an IDE, a team of developers can work on modules of programs simultaneously on the same project, and it is a preferred working environment for developers.
Why become a JavaScript Developer
JavaScript is a versatile programming language allowing users to perform multiple tasks simultaneously.
Once fully mastered, programmers can effectively work on both the client-side (front-end) and server-side (back-end).
JavaScript is also known for its simplicity, and it's practically easy to implement; it helps in saving developers a lot of money when creating a dynamic website.
In other programming languages, such as Java, plenty of time is required for execution, but in JavaScript, you can modify your codes without complication or interpretation.
JavaScript is another client-side script that speeds up program execution by removing the need for server connections.
JavaScript carries out Form validation that can be done offline without waiting for an internet connection or server site. Eternal libraries (JQuery, Bootstrap, Dojo Toolkit) and frameworks(Angular, Backbone.js, React) are used to save time and perform specific tasks with just a few predefined snippets of code.
Perks of Becoming a JavaScript Developer
JavaScript is developing a fully responsive/dynamic website where you can temporarily store client information or data on the system; for example, this can be seen on a banking website, online-shopping website, flight booking site, etc.
Developers create fantastic 2D and 3D games with frameworks of JavaScript, like Phaser, Babylon.js, and Three.js. The Ubisoft and Gameloft platform are good examples of some games developed with JavaScript.
As you can see, in becoming a pro, there is no limit to what can be built with the JavaScript programming language.
