Methods

  • Returns IterableIterator<bigint>

  • at(index: number): undefined | bigint
  • Takes an integer value and returns the item at that index, allowing for positive and negative integers. Negative integers count back from the last item in the array.

    Parameters

    • index: number

    Returns undefined | bigint

  • 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.

    Returns internal.BigUint64Array

  • Yields index, value pairs for every entry in the array.

    Returns IterableIterator<[number, bigint]>

  • every(predicate: ((value: bigint, index: number, array: internal.BigUint64Array) => boolean), thisArg?: any): boolean
  • Determines whether all the members of an array satisfy the specified test.

    Parameters

    • predicate: ((value: bigint, index: number, array: internal.BigUint64Array) => boolean)

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

    • Optional thisArg: 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.

    Returns boolean

  • Changes all array elements from start to end index to a static value and returns the modified array

    Parameters

    • value: bigint

      value to fill array section with

    • Optional start: number

      index to start filling the array at. If start is negative, it is treated as length+start where length is the length of the array.

    • Optional end: number

      index to stop filling the array at. If end is negative, it is treated as length+end.

    Returns internal.BigUint64Array

  • Returns the elements of an array that meet the condition specified in a callback function.

    Parameters

    • predicate: ((value: bigint, index: number, array: internal.BigUint64Array) => any)

      A function that accepts up to three arguments. The filter method calls the predicate function one time for each element in the array.

    • Optional thisArg: 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.

    Returns internal.BigUint64Array

  • find(predicate: ((value: bigint, index: number, array: internal.BigUint64Array) => boolean), thisArg?: any): undefined | bigint
  • Returns the value of the first element in the array where predicate is true, and undefined otherwise.

    Parameters

    • predicate: ((value: bigint, index: number, array: internal.BigUint64Array) => boolean)

      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.

    • Optional thisArg: 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 | bigint

  • findIndex(predicate: ((value: bigint, index: number, array: internal.BigUint64Array) => boolean), thisArg?: any): number
  • Returns the index of the first element in the array where predicate is true, and -1 otherwise.

    Parameters

    • predicate: ((value: bigint, index: number, array: internal.BigUint64Array) => boolean)

      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, findIndex immediately returns that element index. Otherwise, findIndex returns -1.

    • Optional thisArg: 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 number
