Immutable collections and tools for TypeScript
Rimbu is a TypeScript library focused on immutable, performant, and type-safe collections and other tools. Its main aim is to allow programmers to create safe and performant programs without getting in the way. It is inspired by various other collection libraries, mainly Java’s Guava library, the Java 8 Collection library, and Scala’s collection library plus various ideas from the Scala community.
Quick overview of features and benefits
- Extensive set of collection types to cover many problems that would otherwise require more coding to solve.
- Advanced typing uses the TS compiler to offer strict type inference without much explicit typing, and to prove collection non-emptiness.
- Avoid ‘monad’ style programming / chaining (e.g. using types like Option) by offering flexible fallback options for simple methods that can ‘fail’.
- No external dependencies.
- Provides sane defaults but allows extensive customization and configuration.
- A novel and efficient immutable random-access List implementation.
