Something changed between Typescript 4.0.x and 4.1.x and I'm mystified. Previously I was able to generate pure ES3 from ES(whatever) code. I'm developing in Visual Studio Code.

This is my tsconfig.json

{ "compileOnSave": true "compilerOptions": { "allowSyntheticDefaultImports": false, "target": "ES3", "lib": ["ESNext"], "moduleResolution": "node", "module": "es2015", "types": [".\\types"], "removeComments": true
