JS101: A Beginners Guide To Javascript

What is JavaScript?

Javascript is a extremely potent client-side scripting language. JavaScript is mostly used to improve user engagement with websites. In other words, JavaScript can make your website more engaging and dynamic. Additionally Javascript is popular in the creation of mobile applications and games.

Javascript History

Brendan Eich created JavaScript in 1995, and it first debuted in Netscape, a well-liked browser at the time. LiveScript was the original name of the language before being changed to JavaScript.

Many programmers mistakenly believe that JavaScript and Java are similar. In the real world, JavaScript and Java have relatively little in common. JavaScript is merely a scripting language, but Java is a more complicated programming language.

How to Run JavaScript?

Because it is a scripting language, JavaScript cannot operate independently. In actuality, JavaScript code is run by the browser. JavaScript is transmitted to the browser when a user requests an HTML page having JavaScript on it, and the browser is then responsible for running the script.

The fact that JavaScript is supported by all current web browsers is its biggest advantage. Therefore, it is unnecessary for you to worry about whether a visitor to your website prefers Internet Explorer, Google Chrome, Firefox, or any other browser. JavaScript will be made available. Additionally, JavaScript functions on all OSes, including Windows, Linux, and Mac.
