It is designed for creating network-centric applications. It is a lightweight, interpreted programming language. It is complementary to and integrated with Java. it is very easy to implement because it is integrated with HTML. It is open and cross-platform.

What is JavaScript?

JavaScript is one of the most popular and used programming languages in the world. It is a lightweight, interpreted, open, and cross-platform programming language. JavaScript is a complete object-based scripting language produced by Netscape for use within HTML documents and enables interactions with web pages in various unique ways.

JavaScript became an independent language with its own specification called ECMAScript, which is an implementation of the ECMAScript standard.

What JavaScript Can do For us?

JavaScript is basically used to make the web pages dynamic, and interactive, and also add special effects on a page such as a rollover, rollout, and many graphics. such as

1. Used to insert dynamic text into the HTML (ex: Name, Address, etc.)
2. react to events (for example, load the page only when the user clicks on a button)
3. JavaScript is also used to fetch information about the user’s computer such as which browser the user using.
4. It is also used to perform some calculations on the user’s machine such as validating the user input.
5. Animated/dynamic drop-down menus
6. Displaying clock, date, and time
7. Get and set cookies, ask questions to the visitor, and show messages.
8. Remember the data/info on the client-side (“local storage”).

JavaScript is a CS (Client-Side) scripting language. It is in no way related to Java as its name implies, but it is used for client-side scripting. Client-Side scripting, means the ability to manipulate data, the DOM, and a webpage as a whole, without having a backend service or language.

We can make calculations, validate a form or any input field, include some logic that runs when a condition is met, also can manipulate the webpage, and add a lot of functions to a website without any SS (Server-Side) language.

With the introduction of frameworks like Node.js, JavaScript started using server-side technology. Node.js changed the way JavaScript was used. It allows the use of JavaScript on the server-side while APIs, which lead the MEAN way for developing software where secured, the database-connected apps could be written using JavaScript.

With the new development, not only web-based applications can be developed using JavaScript, even desktop-based (Electron), hybrid mobile apps (Ionic), the real-time app can be developed as well. It’s the only language used on the client-side which is supported by all browsers. The complete JavaScript implementations are made up of three distinct parts:

1. The Core(ECMAScript)
2. The Document Object Model(DOM)
3. The Browser Object Model(BOM)

Prerequisites:

You should have some or little knowledge of HTML before learning JavaScript. A JavaScript program can be typed in the head section or in the body section of the HTML page or it could be attached externally to the web pages.
