What is this operator in Javascript ?

This is a question that I'm asking often, so I created this in order to create an operator lookup!

Moreover, it's too complicated to find some operator in google since it ignore "special characters"!

How to use it?

1. Open pannel commands

For Windows/Linux : Press Ctrl + Shift + P

For Mac : Press CMD + Shift + P

2. Enter command

Enter what-is

2. Put the operator

Enter the operator to check!
