E0194: missing parentheses around left-hand side of **; ** operator cannot be used after unary - without parentheses

JavaScript does not allow unary operators left of a ** expression. It is a syntax error to write unary -, +, !, or ~ before a ** expression:

function parity(n) {
  return -1 ** n;
}

function notbit(bit) {
  return ~2**bit
}

To fix this error, write parentheses around the left-hand side of the ** expression:

function parity(n) {
  return (-1) ** n;
}

Alternatively, write parentheses around the ** expression:

function notbit(bit) {
  return ~(2**bit)
}

Introduced in quick-lint-js version 2.0.0.
