Encountering an issue
Having trouble with Type '(number | undefined)[]' is not assignable to type 'number[]'.
whenever attempting to implement
const nums: number[] = [...'a'.matchAll(/a/g)].map(match => match.index);
despite no mention of this property being optional on MDN. Could this be a bug or am I overlooking something?
This TypeScript bug has been causing trouble for developers since 2020. To work around it, simply make sure to confirm that match.index is of type number.
