Deep Cloning Objects in JavaScript, the Modern Way
Instead of the "deep path properties" syntax, you might want to take the opportunity to learn about functional lenses with monocle-ts

I may have a crush on the TypeScript compiler, because of stuff like this
You may be interested also in checking out the implementation of Lens in monocle-ts, one of the libraries in the fp-ts ecosystem

Haskell Lens Tutorial by Exercises
For anyone - anyone who's faffed around with JavaScript's spread syntax when working with nested immutable data, anyway - struggling to understand the general concept or utility of lenses, I'd encourage looking into monocle-ts. The motivation [0] that kicks off the README instantly made me a believer, and TypeScript's idiosyncratic type system makes using the library remarkably natural; it fits right in without needing to deal with anything analogous to Template Haskell.

Is there a cleaner way to immutably update a deeply nested attribute? (I feel like this is not very clean)
You could have a look at the monocle-ts library. It was designed to deal with this kind of problem.

Why is it so difficult to modify a deeply nested state in React?
lenses help with this quite a bit, check out monocle-ts

You could have invented lenses!
You notice that Getters are composable as they are just pure functions, but the fact that setters are mutating values is not that nice. Tho, at this point we have invented quasi mutable lenses and If you really want you might invent actual purely functional lenses as well, but that’s for another day. Meanwhile you can take a look at an actual typescript lesses library from @gcanti / monocle-ts.

Update one of the objects in array, in an immutable way
I'm OK to use any of the libraries immutability-helper, immutable-js etc or ES6. I've tried and googled this for over 4 hours, and still cannot wrap my head around it. Would be extremely grateful for some help.

How to Create Custom Form Validation in React with Yup
This tutorial uses the create-react-app as the starting template. The react and react-dom dependencies are both version 17.0.2. The react-scripts is version 4.0.0. The yup library is the fourth dependency and it is version 0.32.9. The fifth and last dependency is immutability-helper, version 3.1.1.
