Function partition

partition<T, U>(
arr: T[],
predicate: (value: T, index: number, array: T[]) => value is U,
): [falsey: Exclude<T, U>[], truthy: U[]]
Partition an array into two arrays based on a predicate.
Type Parameters
- T
- U
Parameters
- arr: T[]
  Array to partition.
- predicate: (value: T, index: number, array: T[]) => value is U
  Predicate function to partition by.
Returns [falsey: Exclude<T, U>[], truthy: U[]]
A tuple of [falsey, truthy], where falsey contains all elements for which predicate returned falsey, and truthy contains all elements for which predicate returned truthy.
