“OpenTelemetry.js” is written in typescript and they thought putting argument types on functions would protect them from bad inputs and thus “1” + 1 problems. Only none of that happens when calling it from JavaScript.
Somewhere in our half million line (I actually don’t know, because we didn’t have a monorepo) application someone turned a stat into a string and I never did track it down.
When we migrated from StatsD that became a problem.
