Modern JS not transformed to ES3 about bolt-cep

[Klustre]

Yes, I'm successfully using the babel-preset-extendscript, but only with simple tests. Haven't used it in production yet. The core-js-pure library successfully transforms and ponyfills (no global scope pollution), but found esbuild uses nested ternaries which throw an error in Extendscript.

I've been using babel-preset-extendscript in my setup, but it only supports most ES2015 features. core-js-pure has a ponyfill feature, but I haven't been able to have the bundler produce valid Extendscript (likely because of nested ternaries).

Hey @Klustre, I did look into modern array functions to ES3 a while back but didn't find any reliable way to polyfill these on transpilation. Are you saying one those libs did support modern array functions to ES3?

[Silly-V]

I have been just using some polyfill code and it works just fine, what you speak of is probably more advanced and proper.

@Klustre Appreciate the suggestion! I've done some testing with these methods and I don't think I'll include these in the boilerplate for the time being. I have a util library for most common array methods in the utils.ts file.

If you want to add to your own clone, you can by installing and adding babel-preset-extendscript to babel presets array in vite.es.config.ts, but you'll need to adjust the tsconfig to not show errors with modern array methods.

@Klustre revisited this and added a simple implementation for Ponyfills in Rollup.

Built-in Ponyfills have been implemented in 0.4.0 and you can add your own custom ones (see the Readme for details).
