Equal Operators: The Case of Mistaken Identity in JS

| Comments

A little tidbit I learned about Javascript and the equal operator:

’=’ denotes assignment.

Example: var x = 10;

’==’ compares two values and returns a boolean (true or false).

Example: 10 == ‘10’ // returns true

’===’ compares both the values AND the type of the data.

Example: 10 === ‘10’ // returns false

It’s important to know which operator to use to get the results you expect!
