Type declaration

    • <S extends LabelItemModel>(
          predicate: (
              value: LabelItemModel,
              index: number,
              obj: LabelItemModel[],
          ) => value is S,
          thisArg?: any,
      ): undefined | S
    • Returns the value of the first element in the array where predicate is true, and undefined otherwise.

      Type Parameters

      Parameters

      • predicate: (value: LabelItemModel, index: number, obj: LabelItemModel[]) => value is S

        find calls predicate once for each element of the array, in ascending order, until it finds one where predicate returns true. If such an element is found, find immediately returns that element value. Otherwise, find returns undefined.

      • OptionalthisArg: any

        If provided, it will be used as the this value for each invocation of predicate. If it is not provided, undefined is used instead.

      Returns undefined | S

    Type Parameters

    Parameters

    • predicate: (value: LabelItemModel, index: number, array: LabelItemModel[]) => value is S

    Returns LabelItemModel

  • Parameters

    Returns LabelItemModel

  • Calls the specified callback function for all the elements in an array. The return value of the callback function is the accumulated result, and is provided as an argument in the next call to the callback function.

          currentIndex: number,
          array: LabelItemModel[],

    Returns U

  • Returns a copy of a section of an array. For both start and end, a negative index can be used to indicate an offset from the end of the array. For example, -2 refers to the second to last element of the array.

    Parameters

    • Optionalstart: number

      The beginning index of the specified portion of the array. If start is undefined, then the slice begins at index 0.

    • Optionalend: number

      The end index of the specified portion of the array. This is exclusive of the element at the index 'end'. If end is undefined, then the slice extends to the end of the array.

    • OptionalthisArg: any

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