What is JavaScript?
JavaScript is a scripting or programming language that allows you to create dynamic websites or web applications. These applications can be used by any website, regardless of the device or operating system on which it runs.
You must know that dynamic websites are websites that change as they are used, typically depending on the actions taken by users. JavaScript is used to write programs that carry out actions on web pages.

JavaScript was designed by John Resig and released in 1995.
What are the elements of the JavaScript Program?
JavaScript program consists of a list of programming statements or instructions. These statements or instructions contains values, operators, expression, keywords like for loop, while loop, etc.
Statements of JavaScript are grouped in the code block in curly brackets which is the form of function in JavaScript.
What is JavaScript used for?
JavaScript is majorly used for web-based applications and web browsers. Besides it, JavaScript is also used in software, servers, etc. Below are the following areas in which JavaScript is used –
- To add dynamic behavior to web pages -
There is an unlimited way to use JavaScript in web pages that allow user to interact with web pages e. g. - dropdown menu in the website nav bar, showing and hiding the block on button click, a slideshow of images, changing the color of the button or HTML element on mouse hover, audio, and video playing, showing animations, etc. - Building the mobile and web applications -
You can use many available JavaScript frameworks to develop or build mobile and web applications. There are many popular JavaScript framework are available for this g. –Angular, Vue, React, etc. - To develop the web server and related applications -
You can build simple web servers and develop the backend application using the world's popular Node.js. - To build the game application -
You can develop and build browser-based games in JavaScript.
What is a JavaScript framework?
JavaScript frameworks are a versatile way to structure and organize code, making it easy for you to get started.
There are several different JavaScript frameworks available for download, each with its own strengths and weaknesses. Some of the most popular frameworks include AngularJS, ReactJS, VueJS, and KnockoutJS.
Majorly there are three JavaScript types -
- front-end (the forefront layer),
- back-end (the layer below the front-end), and
- mobile apps (an extension of JavaScript that runs on smartphones).
Each type has its own strengths and weaknesses which can impact how effective your code will be on different platforms. For example, mobile apps tend to require more coding time than front-end applications do; however, they can also be more versatile due to their ability to run in different browsers and devices without any problems.
By choosing the right framework for you, you can take your development experience to the next level. When choosing a JavaScript framework, it’s important to take into account your needs.
For example, if you’re primarily a front-end developer, then a framework like React or Angular might be better suited for you. If you’re more interested in using backend technologies like Node.js or ExpressJS, then another framework like Vue might work better for you.
