Unnecessary type checking

[Jameskmonger]

Hi @gunar,

I'm not sure the type check (typeof isCrushed.name === 'string') is necessary here:

if (
  process.env.NODE_ENV !== 'production' &&
  typeof isCrushed.name === 'string' &&
  isCrushed.name !== 'isCrushed'
) {
  console.log('You are currently using minified code outside of NODE_ENV === \'production\'.')
}

By using the strict not-equals (!==) in the next check, we are guaranteeing that isCrushed.name has the same type as 'isCrushed', which is a string. Therefore the explicit type check is unnecessary.
