Function arrToMap

arrToMap<T>(
values: ArrayLike<T> | Iterator<T, any, undefined> | Iterable<T>,
keySelector: ArrToMapKeySelectorFn<T>,
): { [key: string]: T }
Creates an object map from array-like, iterator or iterable values.

Keys are generated in stable source order via keySelector; later duplicate keys overwrite earlier values. Unsafe keys (__proto__, constructor, prototype) are ignored.
Type Parameters
- T
Parameters
- values: ArrayLike<T> | Iterator<T, any, undefined> | Iterable<T>
- keySelector: ArrToMapKeySelectorFn<T>
Returns { [key: string]: T }

Example
```
const users = [
  { id: "u1", name: "Ada" },
  { id: "u2", name: "Lin" },
  { id: "u1", name: "Ada Updated" }
];

arrToMap(users, (value) => value.id, (value) => value.name);
// { u1: "Ada Updated", u2: "Lin" }
