▲ 7 ▼ Running gofmt in Browser with 10 Lines of Code

I saw a message in Gophers Slack #general chat that stood out to me:

but running gofmt in the browser is, um, hard

The context was that they had a 100%-client-side JavaScript application that produced some Go code, but the Go code wasn't gofmted.

"Wait a minute, that's not hard," I thought. "It's trivial! Getting gofmt to run in the browser? I bet I could do it in 10 lines of code!"
