| 4 | * This method is like `_.isEqual` except that it accepts `customizer` which |
| 5 | * is invoked to compare values. If `customizer` returns `undefined`, comparisons |
| 6 | * are handled by the method instead. The `customizer` is invoked with up to |
| 7 | * six arguments: (objValue, othValue [, index|key, object, other, stack]). |

| 13 | * @param {*} value The value to compare. |
| 14 | * @param {*} other The other value to compare. |
| 15 | * @param {Function} [customizer] The function to customize comparisons. |
| 16 | * @returns {boolean} Returns `true` if the values are equivalent, else `false`. |
| 17 | * @example |
| 18 | * |
| 19 | * function isGreeting(value) { |
| 20 | * return /^h(?:i|ello)$/.test(value); |
| 21 | * } |
| 22 | * |
| 23 | * function customizer(objValue, othValue) { |
| 24 | * if (isGreeting(objValue) && isGreeting(othValue)) { |
| 25 | * return true; |
| 26 | * } |
| 27 | * } |

| 30 | * var other = ['hi', 'goodbye']; |

| 32 | * _.isEqualWith(array, other, customizer); |
