Methods

copyWithin

  • copyWithin(target: number, start: number, end?: number): this
  • 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.

      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.

    Returns this

every

  • every(callbackfn: function, thisArg?: any): boolean
  • Determines whether all the members of an array satisfy the specified test.

    Parameters

    • callbackfn: function

      A function that accepts up to three arguments. The every method calls the callbackfn function for each element in array1 until the callbackfn returns false, or until the end of the array.
