Defining JavaScript

JavaScript is a scripting or a programming language, allowing developers to perform complex features on web pages. Initially, this language was created for making web pages alive. In JavaScript, the programs are called scripts. One can write them in the HTML of a web page, then it will automatically run once the page loads. At this point, JavaScript is completely different from another language, called Java.

Initially, when JavaScript was created, it was called “LiveScript”. Then, as Java was extremely popular in that period, then it was decided to call it JavaScript to position it relative to Java. But, over the years, JavaScript has transformed into a completely independent language, with its specification, known as ECMAscript, having no relation to Java. Modern JavaScript can both work in the browser and on the server. Basically, it can run on any device that has a specific program known as the JavaScript engine.
