Basic Usage
Async/Await
Welcome to ES7! ⎝( OωO)⎠
import { create } from 'difficulty';
(async () => {
try {
const difficulty = await create();
const a = difficulty.getLevel('apple');
const b = difficulty.getLevel('cappuccino');
console.log(`apple is level ${a}, easy!`);
console.log(`cappuccino is level ${b}, too hard!`);
} catch(err) {
console.error(err);
}
})();
Output
apple is level 0, easy!
cappuccino is level 3, so hard!
Old schooler?
const Difficulty = require('difficulty');
// Using Promise
Difficulty.create().then((difficulty) => {
...
});
// Sync is available too!
const difficulty = Difficulty.createSync();
