How can I use return in javascript

function, javascript, return

Solution

You can't. That's not the way `return` works. It exits only from the current function.

Being able to return from a function further up the call stack would break the encapsulation offered by the function (i.e. it shouldn't need to know where it's being called from, and it should be up to the caller to decide what to do if the function fails). Part of the point of a function is that the caller doesn't need to know how the function is implemented.

What you probably want is something like this:

function hello1() {
    function hello2() {
        if (condition) {
            return false;
        }
        return true;
    }

    if (!hello2()) {
        return;
    }
}
