Methods

  • Returns IterableIterator<number>

  • Returns the item located at the specified index.

    Parameters

    • index: number

      The zero-based index of the desired code unit. A negative index will count back from the last item.

    Returns number

  • 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 Float16Array

  • Returns an array of key, value pairs for every entry in the array

    Returns IterableIterator<[number, number]>

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

    Parameters

    • predicate: ((value: number, index: number, array: Float32Array) => unknown)

      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 a value which is coercible to the Boolean value false, or until the end of the array.

        • (value: number, index: number, array: Float32Array): unknown
        • Parameters

          • value: number

          Returns unknown

    • 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: number

      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 Float16Array

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

    Parameters

    • predicate: ((value: number, index: number, array: Float32Array) => any)
