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.
What is JavaScript?
JavaScript specifically an object-oriented scripting language and utterly dynamic programming language that can use to add interactivity to a website. A scripting language is a lightweight programming language, it's consists of lines of executable computer code. JavaScript is usually embedded directly into HTML Pages, it supports server-side scripting also, separately known as Livewire.
- JavaScript was developed by Netscape Corporation known as "Live Script".
- First support in Netscape Navigator 2.0.
- It's also known as a scripting tool.
- JavaScript is a freely typed language.
- JavaScript is used to create interactive content.
- It was originally developed in the mid-1990s, it wall called ActionScript.
- The objective behind the development of Javascript is Client-side development.
Why use JavaScript?
JavaScript is a text based programming language used both on the Client-side and server-side platform and JavaScript (JS) specifically an object-oriented scripting language and utterly dynamic programming language that can use to add interactivity into a website. There are the features of JS.
- JS gives HTML Designers a programming tool.
- Js use for improving the design into web pages.
- JavaScript enhanced Web Pages with dynamic and interactive features, it's run in client software.
- JavaScript (JS) language syntax is pretty similar to the C programming language but naming conventions are similar to Java Programming Language.
- It have In-Built Function.
- JavaScript is a Object-Based Scripting Language.
- JavaScript provides validation of User's Input.
- client edge Technology.
JavaScript Engine
JavaScript Engine : Each browser uses a different JavaScript Engine like as.
- Mozilla: SpiderMonkey
- Chrome: V8
- Safari: JavaScriptCore
- IE: Chakra
- Edge: Chakra
What is ECMAScript?
ECMAScript known as European Computer Manufacturer's Association. It is a General-Purpose Programming Language and commonly used for client-side scripting on the world wide web. 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. |
| Interpreted. | Transcompiler BABEL. |
