  1. @JustValyk The definite assignment assertion is a feature that allows a ! to be placed after instance property and variable declarations to relay to TypeScript that a variable is indeed assigned for all intents and purposes, even if TypeScript’s analyses cannot detect so. Basically it tells TypeScript that the variable will be assigned before use so it doesn't complain about that.
