Yeah, Python has it as well. I think the only real use of it is code readability since you declare that this variable will never be used.

Starting with Java 21 (I think), they’ve introduced ignored variables, so you can now actually do this:

try {
    operation();
} catch (Exception _) {
    // nice weather, eh?
}

Edit: forgot that this is about JS lel

if (error) {
    continue;
}
