Debugging a client script is quite simple. Using the keyword “debugger;“ in the script it can be easily debugged in the browser debugger itself and any errors/warning can be identified.

For Server Scripts like Scheduled Script, User Event Script, Portlet etc., it is necessary to use NetSuite debugger to debug it.
