    Added in v0.3.4

    Configuration

    rslint.config.ts
    import { defineConfig, js } from '@rslint/core';

  js.configs.recommended,
  {
    rules: {
      'no-extra-bind': 'error',
    },
  },
]);

    Rule Details

    Disallows unnecessary calls to .bind(). If a function expression does not use this, calling .bind() on it is unnecessary. Arrow functions never have their own this binding, so .bind() on an arrow function is always unnecessary.

    Examples of incorrect code for this rule:

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

var x = (() => {
  foo();
}).bind(bar);

var x = function () {
  (function () {
    this.bar();
  })();
}.bind(baz);

    Examples of correct code for this rule:

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

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

var x = f.bind(bar);
