How to get multiple args discord.js

how can i add multiple arguments in discord,js

If you want to take input from the users multiple times then use collecters 

for example : 
  bot send message : please add an Channel ID 
  user send an ID
  bot again send message : please add an author and so 
  
  After all the questions you want to collect data add it to your variables 
  then use collectors.
