List is a TypeScript library providing a fast immutable list data structure implemented with relaxed radix balanced trees. It offers a comprehensive functional API with curried functions, chainable methods, and seamless Ramda integration.

Use cases

• use immutable lists instead of arrays in functional JavaScript code
• avoid accidental mutation bugs in Redux state updates
• get faster functional list operations than native arrays
• use curried list functions with Ramda-style pipelines
• write type-safe list transformations in TypeScript
• tree-shake a lightweight immutable collection library into a bundle

When to choose

• you need immutable, persistent list semantics with strong performance
• you write functional-style code and want currying and Ramda compatibility
• you want a focused library that does one data structure well

When to avoid

• you need many different data structures like maps or sets in one package
• you mainly mutate arrays in place and don't need immutability
• you need a library with frequent updates or large community activity
