PERTAIN_TOProblem

I haven't found a way to do this in TypeScript directly. — Working on a Next.js project I am displaying a list of grouped items with titles. Tension: the double negative "not every item.someProp not null" is really heavy on the cognitive complexity. Outcome: Is there a better way to accomplish this?

PERTAIN_TORootCause

children[0] — a component that receive a couple of children. Tension: My intention here is to create a search component page, that has a form and a table, that can vary on fields and result. Outcome: you can utilize React's context system.

PERTAIN_TOSolution

Since you are using `Union`s, you will ultimately do that which the so called classic packages do: `Union` narrowing. — children: React.ReactElement | React.ReactElement[]. Tension: I can't find a way to retrieve each child with the right type. Outcome: Perform `Union` narrowing.
