New Set methods are missing in types

[KilianB]

What version of Bun is running?

1.1.21+70ca2b76c

What platform is your computer?

Darwin 21.6.0 x86_64 i386

What steps can reproduce the bug?

JSC already includes the new set operators union intersection difference symmetricDifference, but those are not reflected in the types

bun repl
Welcome to Bun v1.1.21
Type ".help" for more information.
[!] Please note that the REPL implementation is still experimental!
    Don't consider it to be representative of the stability or behavior of Bun overall.
> console.log(Set.prototype);
Set {
  add: [Function: add],
  clear: [Function: clear],
  delete: [Function: delete],
  entries: [Function],
  forEach: [Function: forEach],
  has: [Function: has],
  keys: [Function],
  size: [Getter],
  values: [Function],
  union: [Function: union],
  intersection: [Function: intersection],
  difference: [Function: difference],
  symmetricDifference: [Function: symmetricDifference],
  isSubsetOf: [Function: isSubsetOf],
  isSupersetOf: [Function: isSupersetOf],
  isDisjointFrom: [Function: isDisjointFrom],
  [Symbol(Symbol.iterator)]: [Function],
}

What is the expected behavior?

I would expect with the default setup after running bun init for these types to be present and intellisense being able to pick them up.

What do you see instead?

Methods do not get suggested.

Additional information

Included in typescript 5.5 https://github.com/tc39/proposal-set-methods

Set is not a part of bun-types.

try to edit your tsconfig.json:

"target": "ESNext",
"module": "ESNext",
"lib": ["ESNext"],

Set not being part of bun-types might actually be the issue, or some other part of the project setup did not work properly. Maybe I am even confusing how the lib versions get resolved.

I am using your above mentioned setup but still run into the issue that the types are not defined.

// Enable latest features
"lib": ["ESNext", "DOM"],
"target": "ESNext",
"module": "ESNext",

The pr with the types got merged into typescript in May. microsoft/TypeScript#57230
Is this type package automatically updated or are there release intervals for this? Is this maybe an issue with the bun install cache?

Do the type packages depend on the typescript version vscode is picking up or are they standalone packages that are installed on a as needed basis?

run tsc --noEmit. if there is no error in result, this is issue in VSCode. otherwise, try bun update --latest or bun i -D typescript@latest

Do the type packages depend on the typescript version vscode is picking up

yes.

Thanks, this was actually the missing piece. The ts version not correctly being set in vscode.
