Understanding JavaScript

JavaScript is a high-level programming language, initially this language was used to make websites more dynamic. Along with HTML and CSS, JavaScript is now the most popular programming language for developing applications. Make the website more interactive.

JavaScript belongs to the category of scripting languages. What does it mean? One of the main characteristics of scripting languages is that code does not need to be compiled in order to run. Scripting languages use interpreters to translate the code or commands that we write so that the machine can understand them.

That’s why scripting languages don’t require a lot of code to be written in order for a program to run. With just one line of code below you can create a program that displays the text “Hello, World!” to the screen.

console.log(“Hello, World!”);

This is a simple example of javascript programming.

JavaScript History

JavaScript was first created by Brendan Eich, a Netscape employee, in 1995. At that time Netscape was a well-known software company known for its web browser, Netscape Navigator. Brendan Eich was initially asked to create a scripting language like Java but it could be implemented for browsers. He also designed a new programming language using features inspired by Java, Scheme, and Self.

After being adopted outside of Netscape, JavaScript was standardized by the European Computer Manufacturers Association (ECMA). Since then JavaScript is also known as ECMAScript. Even so, many still call it JavaScript to this day.

There are several versions of JavaScript that have been standardized by ECMAScript. From 2000 to 2010, ECMAScript 3 was the version that was widely used when JavaScript was dominating. During this time, ECMAScript 4 is in development with the hope of providing significant improvisation. However, this ambition did not go smoothly so that in 2008 development of ECMAScript was stopped.
