​--------Create external JavaScript file with the extension .js.

--------After creating, add it to the HTML file in the script tag.

--------The src attribute is used to include that external JavaScript file.

---------If you have more than one external JavaScript file, then add it in the same web page to increase performance of the page.

•Example:

JavaScript is a very powerful scripting language, used mainly for enhancing user's interaction with a web page. You can make your web page interactive and livelier, with the help of JavaScript. JavaScript is also widely used in game development and Mobile application development.

​

JavaScript cannot run on its own, because it is a scripting language, rather, browsers are used for running the code. When you request an HTML page with JavaScript in it, the script is sent to the browser and executed by the browser.

​

You will need a text editor to write your code and a browser to display the web pages you develop. Any text editor of your choice can be used including Notepad++, Visual Studio Code, Sublime Text, Atom, or any other text editor you are comfortable with.

 

For browsers, any web browser including Google Chrome, Firefox, Microsoft Edge, Internet Explorer etc. can run JavaScript.

•HTML element encompasses opening tag, closing tag, content (optional for content-less tags) Eg:
