• In meetupController .js instead of variable mLength, please make your variable name more descriptive
• obj is not descriptive enough
• aDate should now be oldDate and bDate should now be newDate

in questionController, also look at qLength, you can make it questionLength, as well as obj can be replaced with something more descriptive

• For your validations, can we use a Library such as validate.js, express validator, etc. to achieve a better result?
  Note: Make all your variable names very descriptive
