I can't seem to find if it's possible to get Code Completion / Suggestions in seperate module.exports files if that makes any sense.
For example in my main js file:
And in my messageCreate.js file:
Well in client event the Code Completion knows that you have a Discord message, in the second picture it doesn't, there it just knows it has a parameter called message. If you would use TypeScript, you would get Code Completion in the module.exports too I believe.
