Perhaps it would be better to merge this into a separate WIP-redesign-branch so that we can thoroughly test it before merging it into master

You both can use the discord channel if you want!

You can make a constants.js file if you want and just add them there!

plus: I fixed one typo and added a link to a question with a missing link

I am also having this issue

in Async and Performance, chapter 5, shouldn't the following question have id:3 as correct answer?

{ question: What is **not** a common use for a web worker?, questionId: '7eg8p9TGqQ8TuMwYzmUv', shouldBeRandomized: true, answers: [ { text: 'Processing intensive math calculations', id: 0 }, { text: 'Sorting large data sets', id: 1 }, { text: 'High-traffic network communications', id: 2 }, { text: 'DOM diffing algorithm', id: 3 }, ], correctAnswerId: 0, moreInfoUrl: 'https://github.com/getify/You-Dont-Know-JS/blob/master/async%20%26%20performance/ch5.md#worker-environment', explanation: 'Web workers do not have access to the DOM', },

Looks like this has been fixed. Closing
