JavaScript Tutorial For Beginners #16 - While Loops

Yo Ninjas, in this JavaScript tutorial I'll be introducing the concept of looping in JS. More specifically, we'll be taking a look at the while loop - the most basic form of loops.

JavaScript loops are a way of repeating sections of code over and over, so that you're not having to re-write code again and again manually. For as long as a specified condition is true, the loop will continue to execute your code.

Be careful not to cause an infinite loop! This can crash your computer.

As always, any questions, fire away :).

I want to say (on the beginner rights) it's been very well explained compare to other sources! The most difficult part of learning javascript is to find a good source to learn from!

I am so happy I can cry right now.
age++, the key that I was missing.
I never realised that with (i=0; i<10; i++)
You can do it with other variables.
It's so simple.

Best videos i have found on the subject, so simple a mare child could understand and that is exactly what you want with a guide. Started my way with codeacademy which was good but i get a much better understanding in a whole with these vids, recomended for everyone that are new to javascript! Big ups to this dude!!! Sub him, he deserves more.

var enemies =10;

while (enemies > 0) {
document.write ("Engaging enemies!");
enemies--;
}

document.write("All enemies destroyed");
