Function sortedIndexBy

sortedIndexBy<T>(array, value, iteratee?): number
This method is like _.sortedIndex except that it accepts iteratee which is invoked for value and each element of array to compute their sort ranking. The iteratee is invoked with one argument: (value).
Type Parameters
- T
Parameters
- array: undefined | null | List<T>
  The sorted array to inspect.
- value: T
  The value to evaluate.
- Optional iteratee: ValueIteratee<T>
  The iteratee invoked per element.
Returns number
Returns the index at which value should be inserted into array.
Example
```
var dict = { 'thirty': 30, 'forty': 40, 'fifty': 50 };

_.sortedIndexBy(['thirty', 'fifty'], 'forty', _.propertyOf(dict));
// => 1

// using the `_.property` iteratee shorthand
_.sortedIndexBy([{ 'x': 4 }, { 'x': 5 }], { 'x': 4 }, 'x');
// => 0
```
