The fix in a1da3b4 sort of dodges the issue a bit, and doesn't quite do what we'd hope it could…, It turns out JSDoc does support destructing via making up a placeholder name.

The reason there’s no first-class support for iterating through objects with Alpine.js’ x-for is that converting a JavaScript Object to an Array is reasonably easy in modern JavaScript (ES6+) environments using Object.keys, Object.values or even Object.entries. Integration Test Codes. Successfully merging a pull request may close this issue. Some kind of inheritance makes sense to me. Complicating things even further, the new @deprecated tag would be ambiguous if appearing on the first signature; overloads are sometimes deprecated individually, but it's also common to deprecate an entire function. As pointed out by @mattyclarkson eslint has trouble with a default value for destructured params. Next we’ll see how to generate TypeScript typing/type declaration file (types.d.ts) from the JSDoc annotations. But the checker says a function is deprecated if any signature is deprecated. If I need to make a type definitions for it (actually I do) with JSDoc Intellisense support, then I have to copy general function description like 10 times. Move refactorings. This is useful for example if we wanted to persist our todos when the user closes the tab and comes back to it later. I'm troubled about that only when writing definitions. Please take a look at this function. Alpine.js sync to localStorage - simple example Alpine.js sync to localStorage - persistent todo app ... How to achieve TypeScript-like behaviour in Vanilla JavaScript using JSDoc and @ts-check in VSCode: that’s the purpose of this post. * * @param {Universe} universe * @returns {Universe} ...

If only so I can avoid merging hard to maintain workarounds like duplicating documentation. For example given the following function/file, you would get an error “Expected 0 arguments, but got 1.” for the ping('foo') call. This will make my definition 3 times longer than source function and also very hard to modify. Active 3 years, ... For an arbitrary time signature, where do the beats go? Sign in * I am a happy foo. * @property {boolean} isReality mean the destination should be the current directory: .. We can the run whole thing with npx.

Post a bounty on it! In this post I'll try to cover everything you need to know to get started with JSDoc. and conversely, that every parameter you -do- have @param tags for are actually in your function signature.
