Module "is-sorted"

Const isSorted

• isSorted<T>(arr: ArrayLike<T>, cmp?: Comparator<T>, start?: number, end?: number): boolean

• Returns true if the given array and its elements in the selected index range (entire array, by default) are in the order defined by the given comparator ({@link @thi.ng/compare#compare} by default).

  remarks

  Always returns true, if effective index range (or array length) has less than two elements. No bounds checking.

  example

  isSorted([3, 2, 1])
  // false
  
  // w/ custom comparator
  isSorted([3, 2, 1], (a, b) => b - a)
  // true
