We should add some tests to cover #7036. They should cover both JavaScript and TypeScript support.
They can probably be added to test/fixtures.
Huge and nice collection and also getting very much appreciated from the community.
It would be great if somebody can translate into English then it will be reaching out to global.

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

const wb = XLSX.utils.book_new();
const ws = XLSX.utils.json_to_sheet([]);
XLSX.utils.book_append_sheet(wb, ws, 'Bug sheet');
ws.A1 = { t: 's', f: 'square' };

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