History of JavaScript

The unlikely story of the web's language

JavaScript was created in 10 days in May 1995 by Brendan Eich while he was working at Netscape.

The Timeline

  • 1995: "Mocha" (later LiveScript, then JavaScript) is released.
  • 1997: The first edition of the ECMAScript standard is published (ECMAScript 1).
  • 2009: Node.js is released by Ryan Dahl, bringing JS to the server.
  • 2015: The release of ES6 (ES2015)—the biggest update to JS, adding classes, arrow functions, and more.
  • Every Year Since: A new version of ECMAScript is released with incremental improvements.

JavaScript is NOT Java

The name "JavaScript" was a marketing tactic by Netscape to capitalize on the popularity of the Java programming language at the time. They share almost nothing in common except some C-style syntax.
