If my wifi config saved then I don't need to try to do wifi.connect()?

but how do I know when to skip this wifi.connect()?

I test for an IP address. This could probably be refined, but generally the ESP8266 connects to wifi quickly or not at all, say if the config is wrong:

if (wifi.getIP().ip != "0.0.0.0") {
  // rest of your code
} else {
  console.log("not connected to wifi");
}
