It was authored has been out there for longer (since 10 years ago), it also Ramda favors simplicity over flexibility. ramda has a bigger community of maintainers. The table shows the the individual lodash.utility packages are smaller until the number of packages rises. The points are a summary of how big the community is and how well the package is maintained. I attribute this to lodash-es being able to share code between functions, whereas single lodash.utility functions are siloed and unable to share code.. How were the utilities selected? Other types are supported if they define .empty, .prototype.empty or implement the FantasyLand Monoid spec. A better and faster Underscore.js. It also performs much better on some operations, of course it doesn't … The fact you less frequently need to explicit mention your data and you don’t need to declare anonymous functions everywhere definitely reduces the amount of noise in your code and makes it fairly cheaper to maintain.
