* This method is like `_.find` except that it returns the index of the first
|
|
* element `predicate` returns truthy for instead of the element itself.

|
* @static
|
|
* @memberOf _
|
|
* @since 1.1.0
|
|
* @category Array
|
|
* @param {Array} array The array to inspect.
|
|
* @param {Function} [predicate=_.identity] The function invoked per iteration.
|
|
* @param {number} [fromIndex=0] The index to search from.
|
|
* @returns {number} Returns the index of the found element, else `-1`.
|
|
* @example
|
|
*
|
|
* var users = [
|
|
