Stop code execution?

Question

I do not want to learn bad habits so therefore this question👍

Is the code below valid and correctly formatted to stop code execution?
Or is it a bypass in some way to prevent code execution?
(Are there more options to stop code execution?)

var num = 0;
function exec1() {
if (num == 1) {
exec2();
} else {
// stop code execution if not equal
console.log("STOP exec!")
return;
}
// continue code execution if equal
function exec2() {
console.log("continue code exec");
}
}
exec1();

Answer 1

✓ yes whenever "return;" bring no results and stop further code execution and this is on if else so there are no other places where Code have to work on;
