Difference Between JavaScript and ECMAScript
In this article, we will learn the difference between JavaScript and ECMAScript. JavaScript and ECMAScript are used somewhat interchangeably, but not quite. JavaScript is a general programming language in general use, and ECMAScript is its standard foundation.
What is JavaScript?
JavaScript was originally called LiveScript, but Netscape renamed it to JavaScript, perhaps due to the hype surrounding Java. JavaScript first appeared in Netscape 2.0 in 1995 under the name LiveScript. The language's general-purpose core has been integrated into Netscape, Internet Explorer, and other web browsers.
The norm of scripting languages such as JavaScript is ECMAScript.
The following are the features of JavaScript ?
-
DOM Manipulation: JavaScript can access and modify HTML elements via the Document Object Model (DOM).
-
BOM (Browser Object Model): Provides access to browser-related functions like window, navigator, and location.
-
Event Handling: Supports event-driven programming to respond to user interactions.
- Asynchronous Programming: Supports AJAX, Fetch API, and Promises.
What is ECMAScript?
The full form of ECMA is the European Computer Manufacturer's Association. ECMAScript is a Standard for scripting languages such as JavaScript, JScript, etc. It is a trademark scripting language specification. JavaScript is a language based on ECMAScript. A standard for scripting languages like JavaScript, and JScript is ECMAScript. JavaScript is considered as one of the most popular implementations of ECMAScript.
The following are the features of ECMAScript ?
- Defines the fundamental structure of JavaScript.
- Introduces fundamental functionalities such as variables, functions, loops, and operators.
- Makes improvements in versions like ES5, ES6 (ES2015), ES7, etc.
