Small module that makes sure your catch, caught an actual error and not a programming mistake or assertion

module.exports = safetyCatch

function isActuallyUncaught (err) {
  if (!err) return false
  return err instanceof TypeError ||
    err instanceof SyntaxError ||
    err instanceof ReferenceError ||
    err instanceof EvalError ||
    err instanceof RangeError ||
    err instanceof URIError ||
    err.code === 'ERR_ASSERTION' ||
    err.name === 'AssertionError'
}

function throwErrorNT (err) {
  queueMicrotask(() => { throw err })
}

function safetyCatch (err) {
  if (isActuallyUncaught(err)) {
    throwErrorNT(err)
    throw err
  }
