+This method is similar to `_.find`, except that it returns the index of the element that passes the callback check, instead of the element itself.
+
+#### Aliases
+*detect*
+
+#### Arguments
+1. `collection` *(Array|Object|String)*: The collection to iterate over.
+2. `[callback=identity]` *(Function|Object|String)*: The function called per iteration. If a property name or object is passed, it will be used to create a "_.pluck" or "_.where" style callback, respectively.
+3. `[thisArg]` *(Mixed)*: The `this` binding of `callback`.
+
+#### Returns
+*(Mixed)*: Returns the index of the found element, else `-1`.
+
+#### Example
+```js
+_.findIndex(['apple', 'banana', 'beet'], function(food) { return /^b/.test(food); });
+// => 1
+```
