Module array/partition

partition

• partition<T>(fn: ArrPred<T>, list: ArrayLike<T>): [T[], T[]]
• partition<T>(fn: ArrPred<T>): (list: ArrayLike<T>) => [T[], T[]]

• Takes a predicate and a array and returns the pair of arrays of the same type of elements which do and do not satisfy, the predicate, respectively.

  example

   partition(includes('s'), ['sss', 'ttt', 'foo', 'bars']);
   //=> [ [ 'sss', 'bars' ],  [ 'ttt', 'foo' ] ]
  

  Type parameters

  • T

  Parameters

  • fn: ArrPred<T>

    A predicate to determine which side the element belongs to.

  • list: ArrayLike<T>

  Returns [T[], T[]]

  An array, containing first the subset of elements that satisfy the predicate, and second the subset of elements that do not satisfy.

• Takes a predicate and a array and returns the pair of arrays of the same type of elements which do and do not satisfy, the predicate, respectively.

  example

   partition(includes('s'), ['sss', 'ttt', 'foo', 'bars']);
   //=> [ [ 'sss', 'bars' ],  [ 'ttt', 'foo' ] ]
