// Use the created functions
const a = fraction(1, 3)
const b = fraction(3, 7)
const c = add(a, b)

console.log('c =', format(c)) // outputs "c = 16/21"
console.log('d =', format(d)) // outputs "d = 7/9"

// Now, when bundling your application for use in the browser, only the used
// parts of math.js will be bundled. For example to create a bundle using Webpack:
//
//     npx webpack-cli ./custom_loading.mjs --output-path custom_loading_bundle --mode=production
//
// Read more about what bundle sizes you can expect here:
