javascript - How do i run same script over and over, with delay between each run?

Question

in order to run a same script multiple times, i currently use ;

For example, i will run something like this

node RocketLaunch.js;node RocketLaunch.js;node RocketLaunch.js

This works great and run my script 3 times back to back. I am wondering is there an easy way i can run these 3 with gap of 1 hour?

Edit - Thank you for the responses, i am new to learning programming so apologize for posting this in JS, since it seems like a non JS question.

More information - The way i want to intend to use it, run this script every 1 hour for lets say 20 hours/times. The entire job takes around 5 minutes after i run the script and i want it to run every hour and do that 5 minutes job.

So perhaps run a command at Bash level, where i can type it 20 times with a delay of an hour. It runs every hour for 20 hours, then i can do the whole thing again.

Answer 1

This is how I typically do this in bash:

for x in {1..3};
do
node RocketLaunch.js
sleep 3600
done

The {1..3} tells the for loop to do this 3 times, and the sleep function takes the number of seconds as its argument. (3600 = 60 seconds * 60 minutes)
