    Parameters

    • Rest ...args: any[]
      Rest

    Returns any[]

  • Returns the this object after copying a section of the array identified by start and end to the same array starting at position target

    Parameters

    • target: number

      If target is negative, it is treated as length+target where length is the length of the array.

    • start: number

      If start is negative, it is treated as length+start. If end is negative, it is treated as length+end.

    • Optional end: number

      If not specified, length of the this object is used as its default value.

      Optional

    Returns mongoose.Types.DocumentArray<T>

  • Determines whether all the members of an array satisfy the specified test.

    Type Parameters

    Parameters

    • predicate: ((value, index, array) => value is S)

      An object to which the this keyword can refer in the predicate function. If thisArg is omitted, undefined is used as the this value.

      Optional

    Returns boolean
