What is the predecessor of the javascript language?

The predecessor of the javascript language is LiveScript.

JavaScript was originally designed by Brendan Eich of Netscape and initially named its scripting language LiveScript. Netscape later renamed it JavaScript after collaborating with Sun. JavaScript was originally inspired by Java and was designed. One of the purposes is to "look like Java", so there are similarities in syntax, and some names and naming conventions are also borrowed from Java, but the main design principles of JavaScript are derived from Self and Scheme . The similarity in names between JavaScript and Java was the result of Netscape reaching an agreement with Sun Microsystems for marketing reasons at the time. Microsoft also launched JScript at the same time to compete with the JavaScript scripting language.

In the early days of development, the standard of JavaScript was not yet determined. During the same period, there were three pillars: Netscape's JavaScript, Microsoft's JScript and CEnvi's ScriptEase. For interoperability, Ecma International (formerly the European Computer Manufacturers Association) created the ECMA-262 standard (ECMAScript), both of which are implementations of ECMAScript, although JavaScript is intended as a scripting language for non-programmers, not as a programmer People use scripting languages ​​to promote and advertise, but JavaScript has very rich features. [10] In 1997, under the coordination of ECMA (European Computer Manufacturers Association), a working group composed of Netscape, Sun, Microsoft, and Borland determined a unified standard: ECMA-262. The complete JavaScript implementation consists of three parts: ECMAScript, Document Object Model, and Browser Object Model. [9]

JavaScript is a registered trademark of Oracle Corporation. Ecma International developed the ECMAScript standard based on JavaScript. JavaScript can also be used in other situations, such as server-side programming (Node.js).
