Javascript is a high-level scripting language used widely for web development. It was created in 1995 and standardized as ECMAScript. Some key points in its evolution include being developed at Netscape in 10 days under the name Mocha and later renamed Javascript, Microsoft's reverse engineering as JScript, and its standardization by ECMA International. Popular JavaScript frameworks from the 2010s onward drove the rise of single-page apps, and continual yearly updates by ECMA have added many new features.
