List
An immutable list with unmatched performance and functional API
An immutable list with unmatched performance and a comprehensive functional API. List is a purely functional alternative to arrays. It is an implementation of a fast persistent sequence data structure. Compared to JavaScript Array List has three major benefits. List is immutable. This makes it safer and better suited for functional programming. It doesn't tempt you with an imperative API and accidental mutations won't be a source of bugs. Since List doesn't allow mutations it can be heavily optimized for pure operations. This makes List much faster for functional programming than arrays. List has a large API of useful functions and offers both chainable methods and curried functions to suit every taste. List follows the naming conventions common in functional programming and has arguments ordered for currying/partial application. -
