The setUint8()
method of DataView
instances takes a number and stores it as an 8-bit unsigned integer in the byte at the specified byte offset of this DataView
.
// Create an ArrayBuffer with a size in bytes
const buffer = new ArrayBuffer(16);
const view = new DataView(buffer);
view.setUint8(1, 255); // Max unsigned 8-bit integer
console.log(view.getUint8(1));
// Expected output: 255
Syntax
setUint8(byteOffset, value)
Parameters
byteOffset
The offset, in bytes, from the start of the view to store the data in.
value
The value to set. For how the value is encoded in bytes, see Value encoding and normalization.
RangeError
Thrown if the byteOffset
is set such that it would store beyond the end of the view.
const buffer = new ArrayBuffer(10);
const dataview = new DataView(buffer);
dataview.setUint8(0, 3);
dataview.getUint8(0); // 3
