TS7028

#What it means

A label such as outer: is only useful as the target of break outer or continue outer. This is reported when allowUnusedLabels is false; it often catches an object literal written where a block was parsed ({ a: 1 } as a statement makes a a label).

#Example

{
  "compilerOptions": {
    "strict": true,
    "target": "es2022",
    "module": "esnext",
    "moduleResolution": "bundler",
    "noEmit": true,
    "allowUnusedLabels": false
  }
}

export function f(xs: number[]) {
  outer: for (const x of xs) {
    console.log(x);
  }
}

index.ts(2,3): error TS7028: Unused label.

#How to fix

• Remove the label.
• If you meant an object literal, wrap it in parentheses or assign it to something.
