One will get immutability and more power but there’s simply more to learn. Lodash also contains a group of functions that target functional programming. Lodash has a group of general purpose utilities for simplifying common programming tasks. Lodash seems to be a drop-in replacement for underscore. It has since become a superset of Underscore, providing more consistent API behavior, more features, more thorough documentation and unit tests better overall performance and optimizations for large arrays/object iteration, and more flexibility with custom builds and template pre-compilation utilities.
