How do I debug CLI applications when implementing them in javascript?

There is a project that creates a javascript application that completes within the CLI.
CLI. I plan to participate in the project from next week.

I am currently reading the source code for that catch-up.

I wanted to debug it in the local environment because there are a few things that bothered me.
I didn't know how to set the breakpoint and check the variables there.

On the web, you can use the browser debug tool to set breakpoints, but
I was looking for the following sites because I thought I would use IDE for the application that will be completed with the CLI like this time.

There seems to be a lot of IDE itself, but I am having trouble knowing which IDE or debugging tool meets this requirement.

If I wanted to verify only a single file, I thought I would use a browser debug tool, but
In this project, files span multiple files and require them, so I would like to do something else if possible.

Thank you for your cooperation.
