Good morning fellow Typescript developers; I hope you had a fantastic weekend. First, I am incredibly excited to announce that we have passed the 100 subscribers mark for this newsletter, and I would like to thank all of you for making this happen. I am aiming for the 200 subscribers mark, and I need your help and support; please share this newsletter with your friends and provide any feedback you have.
This week’s newsletter doesn’t have any challenges or Typescript tips. I was away on holiday last week, but we will be looking at Discriminated Unions in the next issue next week and how we can use them to write better Typescript types.
