ECMA340

ECMA-340 refers to a standard developed by Ecma International for the programming language ECMAScript. Specifically, ECMA-340 is the designation for the fifth edition of the ECMAScript standard, published in 2011. This version is also commonly known as ECMAScript 5 or ES5. It introduced significant features and improvements over previous versions.

Key additions in ECMA-340 include strict mode, which allows for a safer subset of JavaScript by catching common coding errors and unsafe actions. Object.create() was introduced, providing a way to create new objects with a specified prototype. The standard also added Array.prototype.forEach(), Array.prototype.map(), Array.prototype.filter(), Array.prototype.reduce(), Array.prototype.every(), Array.prototype.some(), and Array.prototype.indexOf(). JSON.parse() and JSON.stringify() were standardized for easier handling of JavaScript Object Notation. Additionally, ECMA-340 introduced accessor properties for getters and setters, and properties like trim() for strings. The development of ECMA-340 was a crucial step in standardizing JavaScript, leading to more predictable behavior and enabling developers to write more robust and maintainable code.
