Would you like to clone this notebook?
When you clone a notebook you are able to make changes without affecting the original notebook.
const { value } = require('realar');
const store = value(0)
const add = store.updater((state, num) => state + num)
const inc = store.updater(state => state + 1)
// Subscribe to store updates
store.to(state => console.log(`state ${state}`));
inc(); // in console: state 1
add(4); // in console: state 5
