1.6. ECMAScript

When Navigator 2 made its debut, it provided built-in client-side scripting with JavaScript. Despite what its name might imply, the language was developed at Netscape, originally under the name LiveScript. It was a marketing alliance between Netscape and Sun Microsystems that put the "Java" into the JavaScript name. Yes, there are some striking similarities between the syntax of JavaScript and Java, but those existed even before the name was changed.

Internet Explorer 3 introduced client-side scripting for that browser. Microsoft provided language interpreters for two languages: VBScript, with its syntax based on Microsoft's Visual Basic language, and JScript, which, from a compatibility point of view, was virtually 100% compatible with JavaScript in Navigator 2.
