#Configuration

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

export default defineConfig([
  js.configs.recommended,
  {
    rules: {
      'no-caller': 'error',
    },
  },
]);

#Rule Details

Disallows the use of arguments.caller and arguments.callee. The use of arguments.caller and arguments.callee make several code optimizations impossible. They have been deprecated in future versions of JavaScript and their use is forbidden in ECMAScript 5 strict mode.

Examples of incorrect code for this rule:

function foo(n) {
  if (n <= 0) {
    return;
  }
  arguments.callee(n - 1);
}

[1, 2, 3, 4, 5].map(function (n) {
  return !(n > 1) ? 1 : arguments.callee(n - 1) * n;
});

Examples of correct code for this rule:

function foo(n) {
  if (n <= 0) {
    return;
  }
  foo(n - 1);
}

[1, 2, 3, 4, 5].map(function factorial(n) {
  return !(n > 1) ? 1 : factorial(n - 1) * n;
});
