Quick Start

Let’s jump into using QuantaJS with a simple counter example.

Example: Counter Store

Here’s how to create a reactive counter using createStore:

import { createStore } from "quantajs";

const counter = createStore({
  state: { count: 0 },
  actions: {
    increment() {
      this.count++;
    },
    decrement() {
      this.count--;
    },
  },
});

// Access state
console.log(counter.count); // 0

// Update state
counter.increment();
console.log(counter.count); // 1

counter.decrement();
console.log(counter.count); // 0

What’s Happening?

createStore creates a reactive store with a state object and actions.
The state is made reactive, so changes trigger updates automatically.
Actions like increment and decrement modify the state directly using this.
