How does V8 differ from ECMAScript standards

Question

Can you tell me How does V8 differ from ECMAScript standards?

Answer 1

Here's a comparison between V8 and ECMAScript standards:

Feature	V8	ECMAScript
Definition	V8 is an open-source JavaScript engine developed by Google	ECMAScript is a standardized specification for scripting languages, including JavaScript.
Scope	V8 is responsible for executing JavaScript code in environments like Chrome and Node.js.	ECMAScript defines the rules, syntax, and features of JavaScript, such as data types, operators, etc.
Focus	8 focuses on performance, compiling JavaScript into machine code for efficient execution.	ECMAScript defines the high-level programming language specifications.
Implementation	V8 is a specific JavaScript engine implementation of the ECMAScript standard.	ECMAScript is a standard that can be implemented by different engines (e.g., V8, SpiderMonkey, Chakra).
Compatibility	V8 executes ECMAScript-compliant JavaScript code but can implement extra features beyond the specification.	ECMAScript sets the baseline for compatibility, ensuring features and behavior remain consistent across implementations.
