Hide private members (e.g. methods) from IntelliSense. (Node / JSDoc)

[infacto]

Is there a way to hide private methods from the autocomplete list? For example:

const log = {
  /** @private */
  somethingPrivate: () => {/* ... */},

  info: () => {/* ... */},
  warn: () => {/* ... */},
  error: () => {/* ... */},
  success: () => {/* ... */},
};

This does not work. The method is still shown in list. But with the doc comment label "private".
It should be hidden. Or is there a separate label for this?

Nope, mr bot, this is not a duplicate. My issue is about hiding. The other issue is about weird characters in the method name. But interesting that this user want to see it. In my opinion private members should be hidden from outside like in TypeScript.
Update: Also tried with //@ts-check. Does not work... But great feature to detect e.g. if an object is used like a function or detect undefined variables. Maybe we can include this private-flag?

Having /** @private */ has no semantics. In TS you can use the private keyword, in modern (and upcoming) JS you can use the #-prefix to mark something as private. It will then be hidden from IntelliSense. If you want support for the jsdoc comment, I'd suggest to file an issue directly against TypeScript: https://github.com/Microsoft/TypeScript

#-prefix only works for class members. Private identifiers are not allowed outside class bodies. And I think that /** @private */ should be handled like other labels e.g. /** @param {number} universalAnswer */. Also if this is not "really" private. ... But thanks for the info. VS Code JS IntelliSense comes from TypeScript? Ok, I consider to file an issue there. Thanks.

Update: Other related issue: #22329 and microsoft/TypeScript#14009
The private-tag in doc comment works with classes only. It's ok.
