"Everything in JavaScript happens inside an Execution Context"

Consider Execution Context as a box with 2 Columns as follows:

• Memory Component or Variable Environment:

This is the place where all the variables & functions etc, are stored in the form of key-value pairs.

Code Component or Thread of Execution:

This is where our code is executed one line at a time.

"JavaScript is a Synchronous, single-threaded Language"

• It means JavaScript can execute one command at a time in a specific order.
