On that note – which I completely agree with – it's interesting how readable this is Array.from(dogs) compared to dogs.map() if map wasn't so widely adopted :)

On that note, I'd love to see how performant Array.from() is compared to .map() that I know doesn't perform very well

Now you've inspired a more ambitious project. Building a custom standalone performance measurement tool for Javascript.

It could be something similar to Runkit, but strictly for benchmarking the various methods and approaches to the same end goal. Like which is faster?

capsLockNames = names.map(capitalize)
Enter fullscreen mode Exit fullscreen mode

OR

capsLockNames= []
for x = 0; x < names.length; x++
  capsLockNames[x] = capitalize(names[x]))
Enter fullscreen mode Exit fullscreen mode
