@lumino/algorithm

What is @lumino/algorithm?

@lumino/algorithm is a collection of generic algorithms and data structures for JavaScript. It provides a variety of utilities for working with iterables, sequences, and other common algorithmic tasks.

What are @lumino/algorithm's main functionalities?

Iterating over sequences

The `each` function allows you to iterate over a sequence and apply a function to each element.

const { each } = require('@lumino/algorithm');

const array = [1, 2, 3, 4, 5];
each(array, value => {
  console.log(value);
});

Filtering sequences

The `filter` function creates a new sequence containing only the elements that satisfy a given predicate.

const { filter } = require('@lumino/algorithm');

const array = [1, 2, 3, 4, 5];
const evenNumbers = filter(array, value => value % 2 === 0);
console.log([...evenNumbers]);

Reducing sequences

The `reduce` function reduces a sequence to a single value by applying an accumulator function.

const { reduce } = require('@lumino/algorithm');

const array = [1, 2, 3, 4, 5];
const sum = reduce(array, (acc, value) => acc + value, 0);
console.log(sum);

Mapping sequences

The `map` function creates a new sequence with the results of applying a function to every element in the original sequence.

const { map } = require('@lumino/algorithm');

const array = [1, 2, 3, 4, 5];
const squares = map(array, value => value * value);
console.log([...squares]);

Other packages similar to @lumino/algorithm

lodash

Lodash is a modern JavaScript utility library delivering modularity, performance, and extras. It provides a wide range of functions for manipulating arrays, objects, and other data structures. Compared to @lumino/algorithm, Lodash offers a more extensive set of utilities and is widely adopted in the JavaScript community.

underscore

Underscore is a JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects. It offers similar functionalities to @lumino/algorithm, such as iteration, mapping, and reducing, but is less modular and performant compared to Lodash.

ramda

Ramda is a practical functional library for JavaScript programmers. It makes it easy to create functional pipelines and offers a variety of utilities for working with data structures. Ramda emphasizes immutability and side-effect-free functions, which can be a different approach compared to @lumino/algorithm.
