I'm sure you've heard of the spread operator in JavaScript (...), it's one of the most powerful operators JavaScript offers and can solve many prob...

I see this pattern a lot here on dev. People try to use simple vocabulary, so even beginners can understand the article, but never really mention the correct vocabulary. How do I google more about this thing I just learned if I don't know it's called a variadic function?
I don't even know it's called a variadic function, and never googled it that way, still, get around by googling pass unlimited arguments...
I understand there's are official names for these things, but no beginner will know these or remember these, that's not my goal for this article.
And that's precisely why I think they should be named in articles like this, because knowing the right name for a thing is just as important as knowing it exists.
"unlimited arguments" is both longer and more ambiguous than "variadic". The latter has a clear meaning in programming, so I can bring them up in a conversation and everyone is on the same page, but if I say "unlimited arguments", I'd have to explain what I mean.
Take care of the performance when you're pushing an item :)
I think in most cases the performance won't be exceeded when using it for everyday stuff most of the time I use it it's to push one item in an array smaller than 100, it doesn't really seem to affect things.
But valid point to keep in mind for bigger array
NodeList to Array, you can use Array.from
const result = Array.from(document.querySelectorAll('div'))
// array
Yes but then it wouldn't be a spread use haha.
We can do many of these using other methods.
Dear Chris Bongers，may I translate your article into Chinese?I would like to share it with more developers in China. I will give the original author and original source.
Sure as long as you attribute the original that's fine with me 🤟
The spread operator is one of my favorites, nice post tho
Thanks Kinanee, it's in my top 3 for sure ✌️
In the first examples the equal sign disappeared.
