My Favorite JavaScript Tips and Tricks

Whoa! This post is a Treasure 🥇 Thanks for sharing 🧡

Wow! Such a wonderful list. We should pin it somewhere and force every JavaScript developer to go through this. 😎

event.target.valueAsNumber: I never knew about this neat trick! Learned something new!

I also found isRequired check very clever.

Thanks for writing this article. It's a treausure. 🙏

Great list - lots of lovely little tidbits, especially the isRequired helper function. Love that!

You have to be slightly careful with the default or in 5, though. If age is 0, it will overwrite it (making your new born person object a 35 year old 😉).

A safer, albeit slightly less-well-supported (IE doesn't know about it), way of attacking it is to use the nullish coalescing operator - ?? which returns truthy values such as 0.

Another legendary article born from Mr. Tapas Adhikary's fingers! Thanks!

Amazing tricks! Thanks for sharing 🤠🚀

Thanks a lot for this

Very helpful article Tapas. Thank you 🙏

I'm not sure about the random function, because of the rounding. Check it out: I believe that the min and max values aren't produced as often the other ones.

Cool collection of JS tricks

I like the isRequired trick as it is simply claver and very useful.

Good job Tapas

The default value example isn't the best.. If Jack has just been born he's suddenly 35

great

I think that the output is incorrect of the bullet number 11: let [fruit, ...rest] = emojis; console.log(rest);
