Function forEach

Invokes the given callback for each item in the given iterable.

Example

declare const map: Map<string, MyObject>;
Array.from(map.values()).forEach(obj => obj.doSomething()); // creates a new array unnecessarily
forEach(map.values(), obj => obj.doSomething()); // one-liner but no new array
forEach(map.values(), withCounter((obj, i) => obj.doSomething(i)); // use withCounter for a kind of index
