Recently, we've had a couple of dot-org build failures (mostly due to my i18n work/refactoring): #21559 #21356 #21101 #21358

Reading through the source code, I find places where == or != are used for typeof, and others where === or !== are used. I believe we should choose one and stick with it. I'd be happy to open a PR for this once there is agreement on which choice should be used.
Note: looking at the produced bundles, it seems that with typeof, === is compiled to ==, and !== is compiled to `

Hi, I'm a Redux maintainer. I'd like to offer a couple suggestions.
The current Redux example implementation shows use of reducers with "hand-written" immutable update logic, and has a somewhat complex store configuration. In addition, the project's current "feature folder" structure results in multiple separate files for the

Too wide (and falsy) segregation of GraphQL Types and Resolvers

Fields should be taken in context of parent type, not as standalone information.

I'm aware that this is a bug tracker and not a support system. But there is one place in the official documentation which puzzles me. I just wonder if react-redux team has decided to pick one implementation over another for a specific reason or else.
