b. Originally named Mocha, then LiveScript, and finally, JavaScript.
c. Released in December 1995, as part of Netscape Navigator 2.0.
1996: Adoption and Standardization
a. Microsoft releases JScript, a reverse-engineered version of JavaScript, with Internet Explorer 3.0.
b. Netscape submits JavaScript to ECMA International for standardization.
1997: ECMA-262 Standard
a. The first edition of the ECMAScript (ES) standard is published, providing a specification for JavaScript, JScript, and other related scripting languages.
1999: ECMAScript 3
a. The third edition of ECMAScript is released, adding significant improvements to the language, such as error handling and string manipulation.
2005: AJAX Revolution
a. The term "AJAX" (Asynchronous JavaScript and XML) is coined, marking a new era for JavaScript and web development.
2009: ECMAScript 5
a. The fifth edition of ECMAScript is published, introducing strict mode, JSON support, and improved object manipulation.
2015: ECMAScript 6 (ES2015)
a. A major update to the language, featuring classes, modules, arrow functions, and many other enhancements.
2015-Present: Annual ECMAScript Releases
a. Smaller, annual updates to the ECMAScript standard, ensuring continuous language evolution.
II. Business Drivers
Browser Wars
a. JavaScript emerged during the intense competition between Netscape and Microsoft to dominate the web browser market.
b. The ability to create dynamic, interactive web pages helped both companies distinguish their products.

Web Application Development

a. The rise of web applications increased the demand for a powerful, versatile programming language.
b. JavaScript enabled developers to build complex, user-friendly applications, driving its adoption and growth.
Cross-platform compatibility
a. JavaScript's ubiquity made it an attractive choice for businesses that needed to reach users across various platforms.
Community and Ecosystem
a. The growth of open-source libraries, frameworks, and tools have made JavaScript an appealing choice for developers and businesses.
III. Key Players
Brendan Eich
a. The creator of JavaScript and co-founder of the Mozilla Project, which later spawned the Mozilla Foundation and the popular Firefox web browser.
Netscape Communications Corporation
a. The company that commissioned the development of JavaScript and played a pivotal role in its initial release and adoption.
a. The creator of JScript, which accelerated JavaScript's adoption and influenced the development of the ECMAScript standard.
ECMA International
