— Hold on, gotta clean up the performance test a bit

— There's the list so far

— I think node has assert but I prefer an internal one for consistency

— Ye

— 

// Logs an error message to console if boolean is false,
//  If errorType is set, throws a new error of errorType instead.
function assert (boolean, message, errorType = null) {
  if (!boolean) {
    errorType !== null ? throw new errorType(message) : console.error(message);
  }
}

— I avoid short circuiting myself
