Great article! By the way, the Twitter link doesn't seem to work! 😁

Optional Chaining is a game changer.

Also a typo there you made with Declaring Array.

Good but beware mistypo in reduce example : {1, 2,3,4} instead of [1, 2,3,4]

Hi Jessica, why use var (instead of let/const) curly braces (instead of square brackets) while declaring an array? I'm curious

Thanks for sharing the helpful content, As always.

All the Very best!

Very nicely written article. Your points were clearly articulated. Kudos Jessica
