eslint/no-extra-bind Suspicious

🚧 An auto-fix is planned for this rule, but not implemented at this time.

What it does

Disallow unnecessary calls to .bind().

Why is this bad?

This rule is aimed at avoiding the unnecessary use of bind() and as such will warn whenever an immediately-invoked function expression (IIFE) is using bind() and doesn’t have an appropriate this value. This rule won’t flag usage of bind() that includes function argument binding.

Examples

Examples of incorrect code for this rule:

const x = function () {
  foo();
}.bind(bar);

const z = (() => {
  this.foo();
}).bind(this);

Examples of correct code for this rule:

const x = function () {
  this.foo();
}.bind(bar);
const y = function (a) {
  return a + 1;
}.bind(foo, bar);

How to use

  "rules": {
    "no-extra-bind": "error"
  }
}

import { defineConfig } from "oxlint";

export default defineConfig({
  rules: {
    "no-extra-bind": "error",
  },
});
