Uint8Array.prototype.setFromHex()

The setFromHex() method of Uint8Array instances populates this Uint8Array object with bytes from a hex-encoded string, returning an object indicating how many bytes were read and written.

This method parses the string into a byte array. To convert the string into a single number, use the parseInt() function with radix set to 16 instead.

Return value: read The number of hex characters read from the input string. If the decoded data fits into the array, it is the length of the input string: otherwise, it is the number of complete hex characters that fit into the array. written The number of bytes written to the Uint8Array. Will never be greater than this Uint8Array’s byteLength.

Syntax example: setFromHex(string)
