The getUint8() method of DataView instances reads 1 byte at the specified byte offset of this DataView and interprets it as an 8-bit unsigned integer.
Syntax
getUint8(byteOffset)
Parameters
byteOffset- : The offset, in bytes, from the start of the view to read the data from.
Return value
An integer from 0 to 255, inclusive.
Exceptions

- : Thrown if the
byteOffsetis set such that it would read beyond the end of the view.

Examples
Using getUint8()
const { buffer } = new Uint8Array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]);
const dataview = new DataView(buffer);
console.log(dataview.getUint8(1)); // 1
