Custom loading

import {

} from 'mathjs'

const config = {
  // optionally, you can specify configuration
}

// Create just the functions we need
const { fraction, add, divide, format } = create({

}, config)

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