What’s the best way to use JavaScript if not null to check if a variable is not null?

Hello dear! My recommendation would be to use if (myVar) (checks for truthy values).

This solution is the most general and checks if myVar is a truthy value. It works for any value that is not falsy, including null, undefined, false, 0, NaN, and "". It’s useful if you want to ensure that the value is neither null nor any other falsy value.

javascript

CopyEdit

var myVar = "Hello"; // Can be any value
if (myVar) {
  console.log("myVar is truthy.");
}

But when should you use this? If you’re only concerned with whether a variable has any meaningful value (not null, undefined, false, etc.), this is your way forward.

Thanks!
