Okay sure, here the example for forEach with spread operator is more concise and makes good work use of not needing to pass arguments, with more complex things the syntax gets increasingly bad (in my experience) and now you need to worry about casting DOM elements to an array before using them. One downside of for of is that you don't immediately get the index, but this can be done quite easily withįor const of array.entries()įor of loops work on iterators so you can loop over DOM elements without needing to create an array.įor const btn of document.querySelectorAll('button') Īom(document.querySelectorAll('button').forEach(console.log) I wouldn't pick it just for performance though, as the benefits are minimal, but it's a nice bonus. On top of that, iterators are super fast, so for of will be faster on most cases. I use some Unicorn lints, and avoiding forEach is one of them:įorEach is not bad, but for of loops have nicer syntax (imo) and extended features (break, continue).
