Expression	Default Visibility	Applicable Visibility
function	public	public / internal / private / external
constructor	public	public / internal / private / external
variable	internal	public / internal / private
event	Not applicable	This is always public

I couldn't find a good explanation of each step of signTypedData EIP with examples of inputs and outputs at each step. I wanted this so I could keep track.

Say this is our private key

const privKey = new Buffer(
  "c87509a1c067bbde78beb793e6fa76530b6382a4c0241e5e4a9ec0a0f44dc0d3",
  "hex"
);

	const ethers = require('ethers')

	const standardPath = "m/44'/60'/0'/0";
	const activeIndex = 0;

	function generatePath(index) {
	const path = `${standardPath}/${index}`;
	return path;
	}

	contract ShiftBytes {
	function replaceBytesAtIndex(
	bytes32 original,
	uint256 position,
	bytes1 toInsert
	) public pure returns (bytes32) {
	bytes1 maskBytes = 0xff;
	bytes32 mask = bytes32(maskBytes) >> ((position * 1) * 8);
	return (~mask & original) \| (bytes32(toInsert) >> ((position * 1) * 8));
	}
