How JavaScript works and what is execution context?

"Everything in JavaScript happens inside an Execution Context."

Execution Context can be considered as a big block or container where the core javaScript's content is executed. It has two components:

• Memory Component

• Code Component

Memory Component: This is also known as Variable Environment. It usually contains variables and functions as a key: value pair.

Code Component: This is also known as the Thread of Execution. Here, code is executed one line at a time (Single-threaded).

"JavaScript is a synchronous single-threaded language."

Synchronous single-threaded means Javascript executes code one line in a particular order at a time. It will go to the following lines only after the previous line has been executed successfully.

Summary

• Everything in JavaScript happens inside an Execution Context.

• Execution Context has two components:

  • Memory Component

  • Code Component

    

• JavaScript is a synchronous single-threaded language.
