strictEquals implementation without using === or !== operator

strictEquals.js

function strictEquals(a, b) {
  // If one is NaN, we'll always receive false anyway
  if (Object.is(a, NaN)) {
    return false;
  }

  // -0 and 0 special case
  if ((Object.is(a, 0) && Object.is(b, -0)) || (Object.is(a, -0) && Object.is(b, 0))) {
    return true;
  }

  return Object.is(a, b);
}

module.exports = strictEquals;
