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.
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.
getUint8(byteOffset)
byteOffsetThe offset, in bytes, from the start of the view to read the data from.
An integer from 0 to 255, inclusive.
RangeErrorThrown if the byteOffset is set such that it would read beyond the end of the view.
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
