# Checking for inequality in JavaScript

The operator `!=` checks for inequality. For example, let's check that the variable `test` is not equal to `0`:

`let test = 1; if (test != 0) { console.log('+++'); // it will work } else { console.log('---'); }`

Change the variable value:

`let test = 0; if (test != 0) { console.log('+++'); } else { console.log('---'); // it will work }`

Check if the variable `test` is not equal to `10`.
