@mobily/ts-belt is a TypeScript utility library that provides a collection of helper functions and utilities to streamline development in TypeScript projects. It offers a range of functions for common tasks like data manipulation, functional programming, and type checking, making it easier to work with TypeScript data structures and functions.
Lazy.js is a functional utility library for JavaScript that provides lazy evaluation and immutable data structures. It offers a wide range of methods for working with arrays, objects, and sequences in a functional programming style. Lazy.js allows developers to create efficient data processing pipelines by chaining operations and delaying execution until necessary.
Both @mobily/ts-belt and lazy.js are relatively less popular compared to some other well-known libraries. However, @mobily/ts-belt is gaining popularity within the TypeScript community due to its focus on providing type-safe utility functions.
TypeScript Support
@mobily/ts-belt is specifically designed for TypeScript projects and provides extensive TypeScript support out of the box. It offers type-safe utility functions and has excellent type definitions. On the other hand, lazy.js does not have built-in TypeScript support and may require additional configuration for TypeScript projects.
Functionality
@mobily/ts-belt provides a wide range of utility functions for working with arrays, objects, strings, and more. It focuses on providing type-safe operations and follows functional programming principles. lazy.js, on the other hand, is a functional utility library that provides lazy evaluation and sequence manipulation. It offers a rich set of functions for working with collections and provides a unique lazy evaluation approach.
Performance
In terms of performance, lazy.js is known for its efficient lazy evaluation approach, which can be beneficial for working with large datasets. @mobily/ts-belt also aims for performance optimization, but it primarily focuses on providing type-safe operations rather than performance optimizations.
Community and Documentation
Both libraries have active communities, but lazy.js has been around for longer and has a more established user base. It has comprehensive documentation and a wide range of examples. @mobily/ts-belt is relatively newer and its documentation is still growing, but it has an active community that provides support and guidance.
Maintenance
Both libraries are actively maintained, but lazy.js has not seen significant updates in recent years. @mobily/ts-belt, being a newer library, is actively maintained and regularly updated to support the latest TypeScript features and improvements.
