Fast, modern, and practical utility library for FP in TypeScript.

## Documentation

Full documentation can be found [here](https://mobily.github.io/ts-belt/).

## Features

- πŸš€ built with `ReScript`, which generates highly performant JavaScript code (see the benchmark results [here](https://mobily.github.io/ts-belt/benchmarks/introduction))
- πŸ‘€ provides more readable code, due to the `data-first` approach
- ✨ supports `TypeScript` and `Flow`
- πŸ›‘ helps you write safer code with `Option` and `Result` types
- 🎯 all functions return immutable data (no side-effects)
- 🌲 tree-shakeable
- πŸ“ fully documented
