Join Morten Rand-Hendriksen for an in-depth discussion in this video Loops, part of JavaScript Essential Training.
- You may have noticed that so far in the course…every thing we've done has focused on the singular.…We've created variables, functions and objects,…and added interactivity using events…but all these things have been unique one off things.…In the real world, that is rarely how things work…and, in many cases, we specifically want our code…to do things more than once, usually as many times…as is necessary and sometimes even endlessly.…For this, we have loops.…Loops are quite literally loops.…
We start a process, usually a function,…then, when it's done, we start the process again.…Loops are a vital part of all programming languages…and will play a vital role in most JavaScript code…you'll write, so, we'll dedicate a whole chapter to them.…At their core, loops are simple.…We create some sort of condition and say for as long…as this condition holds, keep running the loop.…The class A example of a loop looks like this.…For (vari=0;i<10;i++){…and then we console.log(i).…
When we run this, it'll spit out zero, one, two, three,…
