Just remember one thing 👇
Everything inside JS happens inside Execution Context
What is Execution Context ?
Execution context is a container which has two components memory component and code component.
- Memory Component ( Variable environment )
- Code Component ( Thread of Execution )
Memory Component
It contains all the variables and functions in key : value pair
Code Component
It is the part of execution context where code is executed one line at a time.
