If array is sorted providing true for fromIndex performs a faster binary search. An empty object is returned for uncloneable values such as functions, DOM nodes, Maps, Sets, and WeakMaps. The customizer is bound to thisArg and invoked with up to three argument; (value [, index|key, object]).Note: This method is loosely based on the structured clone algorithm. This method is like _.forOwn except that it iterates over properties of object in the opposite order. Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, yeah but I wanna avoid puting obj.value twice, destructing needs to use the same names as in the object. How would electric weapons used by mermaids function, if feasible? If no method names are provided all enumerable function properties, own and inherited, of object are bound.Note: This method does not set the "length" property of bound functions.
