Key Difference Between JavaScript and ECMAScript

JavaScript (JS) is an utterly dynamic programming language that can use to add interactivity to a website. JavaScript code runs on a browser only and it is specifically an object-oriented scripting language. JavaScript (JS) language syntax is pretty similar to the C programming language but naming conventions are similar to Java Programming Language. It is a scripting Language with a plain text code. JavaScript also has an extensive list of online sources, documentation, and online forums, we can see its execution in the browser immediately. If we want to make web applications we can learn JavaScript and JS is a language based on ECMAScript.

ECMAScript is the name of the international standard that defines JavaScript and is known as the European Computer Manufacturer's Association. ECMAScript is a General-Purpose Programming Language and commonly used for client-side scripting on the world wide web. ECMAScript had initially released in June 1997 and edition 11 was released in June 2020. ECMAScript language includes structured, dynamic, functional, and prototype-based features. It is standardized by the ECMA International organization in the ECMA-262 and ECMA-402 Specifications.

ECMAScript language includes structured, dynamic, functinal and prototype-based features. ECMAScript is a programming language which is specified in ECMA-262. The specification of the ECMAScript is ECMA-262. ECMAScript is a Scripting language like JavaScript and in another word JavaScript based on ECMAScript. A example of ECMAScript is as under

Comparison Between JavaScript and ECMAScript

JavaScript vs ECMAScript

Client-side Scripting Language. Standard for scripting language like JS.
It is an implementation of ES standard. It is a specification.
It's works on the prototype-based. Used for client-side scripting on the world wide web.
JavaScript programming requires a text editor. JavaScript based on ECMAScript.
It's written in Plain Text. The main aim of ES is to create a format for users of JS.
It is less Secured and developer have to make efforts to secure it's coding. SES stands for secure ECMAScript.
Mainly used for front-end. ES is a subset of JS, it also used for front-end.
