Discussion on: 8 JavaScript Tips & Tricks That No One Teaches 🚀

[Muhammad Talha Akbar]

Great, Garvit! It's always great to know the language so well and bring about these unconventional ways to solve problems. However, it's always recommended to write code that is self-explanatory. And, I find majority of these tricks to be confusing (to an average eye). Use them when you really have to and leave a comment to make your intention clear.

Noted! and thanks for reading the article!

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)

OR

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

🤔🤔🤔

I can tell you for sure that the for loop is way more performant than map. But if you do compare everything, I'm definitely interested to read.
