Maybe, but I think MDN would be even more helpful for beginners. Compare the documentation for JavaScript's Math.pow() on each:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...

https://www.w3schools.com/jsref/jsref_pow.asp

W3 doesn't have much in terms of English explanation, has less examples, and their playground forwards you to another page as opposed to MDN where it's embedded.
