linter: prefer-const false positive on destructure assignment with existing variable #19974
Description
What version of Oxlint are you using?
1.51.0
What command did you run?
npx oxlint
What does your .oxlintrc.json (or oxlint.config.ts) config file look like?
What happened?
Ran oxlint on the following with prefer-const set to "prefer-const": ["error", { "destructuring": "all" }]
let someOuterScopeVariable : string;
async function generatorFunction() {
return {
inner: 'foo',
outer: 'bar',
};
}
async function myFunction() {
let innerScope: string;
// destructure assignment to existing variables
({inner: innerScope, outer: someOuterScopeVariable} = await generatorFunction());
console.info(`${innerScope}, ${someOuterScopeVariable}`);
}
myFunction();And got the false positive report:
× eslint(prefer-const): `innerScope` is never reassigned.
╭─[index.ts:11:7]
10 │ async function myFunction() {
11 │ let innerScope: string;
· ──────────
12 │ // destructure assignment to existing variables
╰────
help: Use `const` instead.
ESLint does not flag on the same configuration.
