Function mapNotNullish

Maps the given iterable to a new array with the given transform function. The result of the transform function will only be included in the returned array, if and only if the result was strictly not equal to undefined or null.

Thus, the returned array can never include undefined or null.

Use this if you want to map and filter simultaneously; avoiding unnecessary loops.

mapNotUndefined

Example

const accounts = [{ id: 0, name: 'A' }, { id: 1, name: null }];
const names: string[] = mapDefined(accounts, account => account.name);
