Kasen
Kasen is the library of collection methods which is inspired by Lodash, Immutable, Rambda, Scala and Elixir.
Note that Kasen is experimental state. APIs can be changed in the future.
What does Kasen mean?
"Kasen" means "underscore" in Japanese :stuck_out_tongue:
Installation
npm install kasen
Import
- ES Modules:
import Kasen from "kasen";
- CommonJS:
const Kasen = require("kasen");
Example
const result1 = Kasen.map({ a: 1, b: 2, c: 3 }, v => v + 1);
console.log(result1); // => { a: 2, b: 3, c: 4 }
const result2 = Kasen([1, 2, 3])
.filter(v => v % 2 === 1)
.map(v => v + 1)
.toJS();
console.log(result2); // => [2, 4]
Feature
Immutability: Methods do not mutate an input collection.
const input = [1, 2, 3]; const result = Kasen.push(input, 4); console.log(input); // => [1, 2, 3] console.log(result); // => [1, 2, 3, 4]
Lazy Evaluation: Method chaining does not process unnecessary calculations.
const result = Kasen([1, 2, 3]) .map(v => { console.log(v); return v + 1; }) .every(v => v % 2 === 0); // => 1 // => 2 console.log(result); // => false
Great Selection of Methods: Kasen will have a lot of collection methods.
- 96 methods for Array.
- 57 methods for Object.
- Light Weight: Kasen will be light weight library.
- Kasen is 68 KB now.
APIs
Note that documentation is under construction.
