Potassium

What this is

Potassium is a library that provides a simple and efficient way to work with data. It allows users to easily manipulate and analyze data using a variety of tools and methods. With Potassium, users can perform tasks such as data cleaning, filtering, and transformation.

Installation

npm install @potassium/core

Key concepts

The most important APIs and patterns in Potassium include:

• Atoms: The basic building blocks of data in Potassium, which can be used to store and manipulate individual values.
• Molecules: Collections of atoms that can be used to represent more complex data structures.
• Reactions: Functions that take in atoms or molecules and produce new values.

Example:

import { atom } from '@potassium/core';

const counter = atom(0);

console.log(counter.get()); // Output: 0

Correct usage patterns

Here are some examples of correct usage patterns in Potassium:

• Creating and updating atoms:

import { atom } from '@potassium/core';

const counter = atom(0);

counter.set(1);
console.log(counter.get()); // Output: 1

• Using reactions to transform data:

import { molecule, reaction } from '@potassium/core';

const data = molecule({ name: 'John', age: 30 });

const greeting = reaction(data, (data) => `Hello, ${data.name}!`);

console.log(greeting.get()); // Output: Hello, John!

Common mistakes to avoid

Some common mistakes to avoid when using Potassium include:

• Not properly updating atoms and molecules, leading to stale data.
• Not handling errors and exceptions properly, leading to unexpected behavior.

File and folder conventions

Potassium projects typically follow standard JavaScript naming conventions and folder structures. Configuration files, such as package.json, should be placed in the root of the project.
