Function uniqBy

uniqBy<T>(array: T[], iteratee: (item: T) => any): T[]
Creates a new array with unique elements determined by the result of an iteratee function.

The iteratee is invoked for each element to generate a key by which uniqueness is computed. Elements that produce the same key are treated as duplicates and only the first occurrence is kept.
Type Parameters
- T
Parameters
- array: T[]
  The array to process.
- iteratee: (item: T) => any
  The function invoked per element to generate the key for comparison.
Returns T[]
A new array containing unique elements based on the computed key.
Example
```
uniqBy([1.2, 2.3, 2.4, 3.1], Math.floor);
// → [1.2, 2.3, 3.1]

uniqBy([{ id: 1 }, { id: 2 }, { id: 1 }], x => x.id);
// → [{ id: 1 }, { id: 2 }]
```
