Type definition wrong?

Just found this project and would love to be able to use linq style code in typescript. However, I think there’s something wrong with the typings file. It’s almost like it’s out of date. Specifically, I’m trying to use the GroupBy changes in 1.12.1. I’ve tried that version and 1.12.2. Both seem to have this in index.d.ts:

GroupBy(grouper: (key: T) => any, mapper: (element: T) => any): any;

I’ll admit that I’m fairly new to typescript, so maybe I’m missing something, but isn’t that the wrong entry?

I wrestled with TypeScript in microbundle including several PRs. I found deeper issues and ended up falling back to Rollup. Wish I could help!

I think the point of shipping it as a TypeScript file is that it gets compiled by the end project, and doesn’t get transpiled to something else in between. There are other implementations (like linqjs) that are frankly a little better in some ways, so this project should play to it’s strengths (more closely mapping to the C# LINQ implementation) and keep things simple. Just ship the TS file. Don’t transpile it, don’t have a separate types file. None of that is necessary. If you’re not using TypeScript in the first place, I don’t think you should be using this library. But that’s just my personal opinion 😃
