Deep merge/clone JavaScript objects. Includes options to filter, inspect, and modify properties, merge and sort arrays, and remove duplicate array items. Properly handles property accessors (getters/setters) and descriptors. Returns new object without mod
Mergician is a flexible, light-weight utility for deep (recursive) merging/cloning of JavaScript objects.
Unlike native methods and other merge/clone utilities, Mergician provides flexible options for customizing the merge process. These options make it easy to filter properties, inspect and modify properties before/after merging, merge and sort arrays, and remove duplicate array items. Property accessors and descriptors are also handled properly, ensuring that getter/setter functions are retained and descriptor values are defined on the newly merged object.
