JXA script stops running when my macbook goes to sleep

Question

I am running a JXA script as an agent using launchctl. The main logic of the script is supposed to be run at intervals of 2 seconds, which I have achieved using an infinite loop and delay. However, whenever my macbook goes to sleep the script stops execution and I have to unload and load the agent manually again.

My script:

for(;;) {
   // (Open browser and check whether a tab exisits or not)
   <APPLICATION LOGIC > 
   delay(2);
}

Can I do something to ensure that this script keeps on running even after my macbook wakes up?

Throw away that script. You don't want it running even when your MacBook is awake, let alone when it's trying to sleep. **DON'T** run stuff on an infinite loop. Either use an AppleScript _stay open_ application with an **`on idle`** handler or, better yet, use `launchd` to run the script, which will deal with recurring the execution of the script properly.

Thanks. Have removed the infinite loop and now I am managing the execution of the script using `launchctl` as recommended. If someone wants to learn how to execute a script every N seconds using `launchd` please refer to the following article: [Run a script every 5 mins on a Mac](https://www.splinter.com.au/using-launchd-to-run-a-script-every-5-mins-on/) — Shubham, Nov 25 '20 at 04:27

Based on the suggestion by CJK, I am now executing my JXA script, every 5 seconds, using launchctl and the following plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>google-meet.job</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/bin/osascript</string>
        <string>/Users/porter/Library/Script Libraries/Brave - Google Meet Running.scpt</string>
    </array>
    <key>StartInterval</key>
    <integer>5</integer>
</dict>
</plist>

You can control the frequency of execution of your script using the StartInterval key.
