💻 Code

/// <reference path="fourslash.ts" />

//// function iterateTuples(tuples: [string, string][]) {
////     tuples.forEach((t) => {})
//// }

verify.baselineInlayHints(undefined, {
  includeInlayVariableTypeHints: true,
  includeInlayParameterNameHints: "all",
  includeInlayFunctionParameterTypeHints: true,
});

🙁 Actual behavior

On TypeScript, this works as intended.

On the TypeScript Go port, we get the error seen in microsoft/typescript-go#2039:

Unhandled case in Node.ElementList: KindTupleType

🙂 Expected behavior

// === Inlay Hints ===
    tuples.forEach((t) => {})
                   ^
{
  "text": "callbackfn:",
  "position": 72,
  "kind": "Parameter",
  "whitespaceAfter": true
}

    tuples.forEach((t) => {})
                     ^
{
  "text": ": [string, string]",
  "position": 74,
  "kind": "Type",
  "whitespaceBefore": true
}
