How to repeat javascript code?

Question

I have an alert() and a prompt() in variables how can i make them repeat?

Answer 1

You need a loop.  If you want them to repeat a specific number of times, you would generally use a for loop.  If you want them to repeat until a specific condition is true or false, you generally use a while loop.  If you want them to repeat forever (why?) you can achieve this with either.

Here are examples:

// to repeat 3 times

for (var i = 0; i < 3; i++) {

  alert('Hello world!');

}

// to repeat endlessly

// I recommend you don't run this; it'll not be a pleasant experience!

while (true) {

  alert('Hello world!');

}
