The purpose of : "if(boolean) return;". in Javascript

Question

Consider the following code:

if(boolean) return;

What is the purpose if this condition?

Is it logically the same as:

if(boolean) { return true; }

Thank you for answering!

Answer 1

return; with no value is equivalent to return undefined;. But it's usually used in functions that aren't expected to return a value, so it just means "exit the function now".

So that code is equivalent to:

if (boolean) {
    return undefined;
}
