# JSFloat64Array constructor

1. @Since.new('3.6')

JSFloat64Array([

1. JSArrayBuffer buffer,
2. int byteOffset,
3. int length

])

Creates a JavaScript `Float64Array` with `buffer` as its backing storage, offset by `byteOffset` bytes, of size `length`.

If no `buffer` is provided, creates an empty `Float64Array`.

## Implementation

    @Since('3.6')
    external JSFloat64Array([JSArrayBuffer buffer, int byteOffset, int length]);
