Introduction to JavaScript

Mozilla’s article “A re-introduction to JavaScript” by Simon Willison is a must-read regarding the programming language. Some highlights:

  • “JavaScript is an object oriented dynamic language; it has types and operators, core objects, and methods. Its syntax comes from the Java and C languages, so many structures from those languages apply to JavaScript as well. One of the key differences is that JavaScript does not have classes.”
  • “JavaScript was created in 1995 by Brendan Eich, an engineer at Netscape, and first released with Netscape 2 early in 1996. It was originally going to be called LiveScript, but was renamed in an ill-fated marketing decision to try to capitalize on the popularity of Sun Microsystem’s Java language — despite the two having very little in common. This has been a source of confusion ever since.”
  • “Microsoft released a mostly-compatible version of the language called JScript with IE 3 several months later. Netscape submitted the language to Ecma International, a European standards organization, which resulted in the first edition of the ECMAScript standard in 1997.”
