The BigUint64Array() typed array constructor creates a new BigUint64Array object, which is, an array of 64-bit unsigned integers in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0n. Once established, you can reference elements in the array using the object's methods, or by using standard array index syntax (that is, using bracket notation).


new BigUint64Array()
new BigUint64Array(length)
new BigUint64Array(typedArray)
new BigUint64Array(object)

new BigUint64Array(buffer)
new BigUint64Array(buffer, byteOffset)
new BigUint64Array(buffer, byteOffset, length)

Note: BigUint64Array() can only be constructed with new. Attempting to call it without new throws a TypeError.
