What is the difference between interpreter and compiler ?

Answer 1

Compiler compiles your code before executing and is faster than interpreter.

Answer 2

generaly compilers turn your code into an executable file, like with c/c++/c#/java(in a way) and other languages, which you can then launch. Interpreter executes your code as it is by itself. Interpreted languages include python, html, js, css

Answer 3

Compiler will go through your whole code before compiling --> it won't compile if there's an error. (example: C#)
Interpreter will read your code line by line, errors can be included and won't stop it from running. (example: php)
