5 | * This method is like `_.sortedIndex` except that it accepts `iteratee`
|
---|
6 | * which is invoked for `value` and each element of `array` to compute their
|
---|
7 | * sort ranking. The iteratee is invoked with one argument: (value).

13 | * @param {Array} array The sorted array to inspect.
|
---|
14 | * @param {*} value The value to evaluate.
|
---|
15 | * @param {Function} [iteratee=_.identity] The iteratee invoked per element.
|
---|
16 | * @returns {number} Returns the index at which `value` should be inserted
|
---|
17 | * into `array`.
|

18 | * @example
|

|
---|
20 | * var objects = [{ 'x': 4 }, { 'x': 5 }];
