Methods

sort

  • sort(a: [any, any], b: [any, any]): number
  • This method is used to determine order of entries when sorting.

    • If return value is a negative value, a comes after b,
    • If return value is a positive value, a comes before b,
    • If return value is 0, a and b are indistinguishable in this sorting mechanism. Their order with respect to each other is undefined. This method must always return the same result given the same pair of keys.

    Parameters

    • a: [any, any]

      first entry

    • b: [any, any]

      second entry

    Returns number
