DataView.prototype.getBigUint64()
The getBigUint64() method gets an unsigned 64-bit integer
(unsigned long long) at the specified byte offset from the start of the
DataView.
Try it
Syntax
getBigUint64(byteOffset)
getBigUint64(byteOffset, littleEndian)
Parameters
byteOffset-
The offset, in bytes, from the start of the view to read the data from.
littleEndianOptional-
Indicates whether the 64-bit int is stored in little- or big-endian format. If
falseorundefined, a big-endian value is read.
Return value
A BigInt.
Errors thrown
RangeError-
Thrown if the
byteOffsetis set such that it would read beyond the end of the view.
Description
There is no alignment constraint; multi-byte values may be fetched from any offset.
Examples
Using the getBigUint64 method
const buffer = new ArrayBuffer(8);
const dataview = new DataView(buffer);
dataview.getBigUint64(0); // 0n
