Discussion on: The Strictest TypeScript Config

Agreed!
In general, as always, it depends on the situation 😁

Just dropping my 2 cents, the possible undefined problem of the aforementioned record can be solved by an explicit cast in the value lookup, it's just that both the object and its key need to be casted.

let obj: Record<string, { func: Function }> = {}

for (let key of Object.keys(obj)) {
  (obj[key] as typeof obj[typeof key]).func(); // ✅
}

Though the case seems rather artificial, as you'd probably be using .values or .entries :P

Hey @bwca !
Thank you for sharing your approach to solving the problem!
I believe it's challenging to assess it solely based on this small code snippet. In real projects, everything can be significantly different 🥲
