Function partition

Alias

partition<T>(arr, isInTruthy): [truthy: T[], falsy: T[]]
Splits an array into two groups based on a predicate function.

This function takes an array and a predicate function. It returns a tuple of two arrays: the first array contains elements for which the predicate function returns true, and the second array contains elements for which the predicate function returns false.
Type Parameters
- T
  The type of elements in the array.
Parameters
- arr: readonly T[]
  The array to partition.
- isInTruthy: ((value: T) => boolean)
  A predicate function that determines whether an element should be placed in the truthy array. The function is called with each element of the array.
  - - (value): boolean
    - Parameters
      value: T
      Returns boolean
Returns [truthy: T[], falsy: T[]]
A tuple containing two arrays: the first array contains elements for which the predicate returned true, and the second array contains elements for which the predicate returned false.
Example
```
const array = [1, 2, 3, 4, 5];
const isEven = x => x % 2 === 0;
const [even, odd] = partition(array, isEven);
// even will be [2, 4], and odd will be [1, 3, 5]
```
