Evanion / exclude-null.ts

Created April 25, 2024 09:51

Excludes `null`, in an object, and replaces it with `undefined` in a way that TypeScript understands it.

	type ExcludeNull<T> = {
	[K in keyof T]-?: null extends T[K] ? Exclude<T[K], null> : T[K];
	};

	/**
	* Filters out any `null` values and makes them `undefined`.
	* It also filters out the type of the object so the TS parser understands it.
	* @param obj Object containing null types
	* @returns
	*/
