Write `validateSend(address, amount, balance)` returning an errors object: `address` key `"Invalid address"` if it doesn't match `/^0x[a-fA-F0-9]{40}$/`; `amount` key `"Enter a positive amount"` if not a positive finite number, or `"Insufficient balance"` if it exceeds `balance`.
Required in your answer: test(Number.isFinite
Transpiled, then run in a sandbox
function validateSend(address, amount, balance) {
// TODO
}
