After the assignment and arithmetic operators, the third set of operators I want to introduce is comparison operators.

They are one of the most important operators category in JavaScript.

Comparison operators always return a boolean, a value that’s true or false, and they are divided in 2 groups: equality operators , and disequality comparison operators.

These are equality operators:

• === checks for equality
• !== checks for inequality

These are disequality comparison operators:

• < means “less than”
• <= means “less than, or equal to”
• > means “greater than”
• >= means “greater than, or equal to”

You can use them to compare two numbers, or two strings.

Note that we also have == and != in JavaScript, but I highly suggest to only use === and !== because they can prevent some subtle problems.
