Is JavaScript Compiled or just Interpreted.

In case it is just an Interpreted Language, it should not support feature like Hoisting, since feature of Hoisting is supported only if the execution Engine know about the Environment.

In case it just Interprets the Code, Environment Information would not be available

Looking for the Theoretical aspect

Javascript is an interpreted language - it is not compiled.
It always uses hoisting, which does not need to know about the environment, it just needs to read the source before it begins interpreting it, and "moves" declarations to the top of the containing scope so they can be used before they are declared.
JavaScript Hoisting[^]
Also see: JavaScript Scoping and Hoisting[^] which has a good explanation of JS scope and hoisting.

V8 compiler in Google Chrome Compile the Code as per it official Documentation.

Is it talking about javascript code compilation or something else.

Introduction · v8/v8 Wiki · GitHub

Please look for the General Introduction of V8 Engine.

When the Engine itself compiles the code, how can javascript be interpretted.

Please help me with the confusion.
