Definition of Done

For every submission to the codebase, check that it meets the DoD below.

• [x] Code fulfils the user story and scenarios set out in the github task and UI prototype.
• [x] The feature has been thoroughly manually tested. (Ask other devs to give some fresh eyes on this as you go.)
• [x] All tests run and passed from terminal. Any broken tests fixed, not disabled or skipped.

  npm test

• [x] Tests added or updated where appropriate. (Be pragmatic about adding new tests, think; how critical is this module or function? If this function broke due to changes, how would it affect the user experience?)
• [x] eslint run and passes. Any issues fixed.

  npm run lint

• [x] PR created in Github.
• [x] Two peer reviews from other devs.
• [x] One peer review from one of the teachers.
• [ ] After all the peer review comments are addressed, the branch is merged to main!

@rongyue1 @yara-gagentorn The console.log seems to have returned in the latest commit, and now there are linting errors around some missing catches. Can you take another look, please?
