Checking for equality in JavaScript

To check two values for equality, use the operator ==. Let's check for example that the variable test is equal to 0:

let test = 0;

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

Change the variable value so that the condition is not met:

let test = 1;

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

Check if the variable test is equal to 10.
