left as var because simulators is used outside the context of the try/catch it's in. Turn it into a const and you get "simulators is not defined" error. You could pull it out of the try/catch, but then you have to use let. So I thought var was actually the best choice here. If you want, I'll add "let simulators;" above the try. What do you prefer?

Ah yes, let simulators outside of the try-catch block would be the preferred style.

This is the part that will honor an empty device name ("deviceName === true") with only one device connected, and use that name. Much easier for testing on a single device with zero side effects.

{
console.log(`Using first available device ${devices[0].name} due to lack of name supplied.`)
return devices[0];
}
for (let i = devices.length - 1; i >= 0; i--) {
if (devices[i].name === deviceName || formattedDeviceName(devices[i]) === deviceName) {
return devices[i];
}
}
}


function matchingDeviceByUdid(devices, udid) {
for (let i = devices.length - 1; i >= 0; i--) {
if (devices[i].udid === udid) {
