Package Exports
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (atomic-fns) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
atomic-fns
Like Lodash, but in TypeScript and for ESNext.
Stop shipping code built for browsers from 2015.
You may prefer this library because:
- TypeScript & docs: Includes type declaration files and js with JSDocs for best in class experience.
- Zero deps: Built from scratch with no runtime dependencies or polyfills.
- ESNext: Uses modern idiomatic syntax, data structures, and control flow techniques.
- Modular: Pick what you need. Supports tree-shaking, no side effects, and works with all bundlers.
- Lazy: Leverage generators, iterators, and functional composition.
- Tests: All modules have comprehensive test suites and 100% test coverage.

Get Started
This library is available as an npm package.
To install the package you need to have npm (or yarn) installed and then run:
npm install atomic-fnsHow to use
Just import any function or class you need.
import { sorted, times, uniqueId } from 'atomic-fns'
times(5, (i) => i)
// -> [0, 1, 2, 3, 4]
sorted([4, 3, 2, 1])
// -> [1, 2, 3, 4]
uniqueId('user_')
// -> 'user_101225005'

Data model
This library features a data model similar to Python but not always. Only the missing parts have been implemented, while respecting the JS standards.
For example, in Python collections, size() is a method, while in JS it's just a property. So this library uses size property instead of method. Similarly, the len function implementation checks for both length and size since many JS objects have a length property.
Special method names
This library adds support for operators using object methods such as:
obj.eq(other)adds customobj == other.obj.lt(other)adds customobj < other.obj.lte(other)adds customobj <= other.obj.gt(other)adds customobj > other.obj.gte(other)adds customobj >= other.obj.compare(other)overloads sorting operations.
When working with objects, functions in this library use these custom operators for equality and sorting. You can also apply operators to values like eq(x, y), lte(x, y), compare(x, y), etc.
New Types
Decimal provides support for correct rounded floating point arithmetic, with arbitrary precision.
This fixes precision issues with float arithmetic, for example:
0.1 + 0.1 + 0.1
// 0.30000000000000004
decimal('0.1').add('0.1').add('0.1').toNumber()
// 0.3Some common base interfaces and typing patterns you may have seen like Optional, Result, Comparable, Iterator, and others.
