Kent C. Dodds shares the backstory of paypal-scripts, a tool that encapsulates all the tools common to PayPal applications and published modules and why TypeScript was a fit. Kent took a poll in their #paypal-scripts Slack channel and 100% of respondents said they wanted the change. Here’s what happened next…

About a week later, I had totally migrated paypal-scripts from supporting Flow to supporting TypeScript (most of that time was making all the tools recognize .ts and .tsx files 🙄 and allowing paypal-scripts to dogfood itself which is kinda tricky 🐶).
…
Then we had Christmas break 🎄 and the week we got back after the new year 🎆, it was merged and now every new project starts off with modern tools that will stay updated by default and will be statically typed with TypeScript.

Kent built two small apps (one for his wife and one for his kids) and didn’t even need to download any source code. His conclusion:

What I love about this is how our tools have leveled the playing field. All of these tools are 100% free so long as you have access to a computer with internet access.

This is a clear example of the web getting better.
