History and Versions (ES5, ES6+)

JavaScript was created in just 10 days in 1995 by Brendan Eich. It was first called Mocha, then LiveScript, and finally JavaScript (no, it’s not related to Java!).

• ES5 (2009): Brought strict mode, JSON support, and more.
• ES6 (2015): A huge update! Added let, const, arrow functions, classes, and more.
• ESNext: New features are added every year!

Fun Fact: The official name for JavaScript is ECMAScript (ES).
