Does return ends function if ifelse is used?

I am returning something inside if else statement. Does it ends whole function or only ifelse scope?

function user () {
    if (//first) {
        return TRUE;
    }
    //somecode

    if (//second) {
        return FALSE;
    }

    return TRUE;
}

In above code if my first condition is true, does it end whole function or only first ifelse scope?
