Ramda is a lightweight and pure functional programming library for working with data in JavaScript. It provides powerful functions for transforming and manipulating lists, objects, and functions with ease. Ramda is designed for point-free, or 'tacit', programming style, reducing the need for code verbosity and making the code more concise and readable. Ramda emphasizes immutability and supports partial application of functions, making it easy to compose functions and create reusable code.

Ramda is a widely popular functional programming library in the JavaScript community. It has been around for a long time and has a large user base. On the other hand, @mobily/ts-belt is a relatively newer library and might not have the same level of popularity and adoption as Ramda.


Ramda is a comprehensive library that provides a wide range of utility functions for functional programming, which makes it larger in size. @mobily/ts-belt, on the other hand, is a more focused library specifically designed for TypeScript projects, and it aims to be lightweight and modular.


Both @mobily/ts-belt and Ramda provide a rich set of functional programming utilities. Ramda has a larger number of functions and covers a wider range of use cases. It has a strong focus on immutability and provides functions for working with lists, objects, and more. @mobily/ts-belt, while being smaller, provides a set of carefully crafted utilities specifically for TypeScript projects, with a focus on type safety and ease of use.

TypeScript Support

While both libraries work with TypeScript, @mobily/ts-belt is specifically designed to provide a seamless experience for TypeScript users. It provides comprehensive typings and takes full advantage of TypeScript's type system, providing a more robust and type-safe development experience. Ramda also has TypeScript typings available but may not have the same level of type safety and accuracy as @mobily/ts-belt.

Developer Experience

Both libraries have well-documented APIs and provide good developer experiences. However, since @mobily/ts-belt is tailored for TypeScript projects, it may provide a more intuitive and TypeScript-friendly API. It also offers better editor support and auto-completion due to its strong TypeScript integration.


Ramda is a mature library with a large community and is actively maintained, ensuring regular updates and bug fixes. @mobily/ts-belt is a newer library but is also actively maintained by its author, providing updates and improvements. It is important to consider the level of community support and maintenance when choosing between the two libraries.
