<p dir="auto">Hello! At the ES6 course by Wes Bos, I learned some more about custom promises.<br /> We reviewed how we can create a custom promise: <pre><code>function breathe(amount) { return new Promise((resolve, reject) => { if() { reject... } <p dir="auto">We use reject if we don't want the function to work for some reason. There is an error for example. <pre><code> breathe(1000).then(res => { console.log(rs);e return breathe(500); }).then(res => {... .... })catch(err => { console.error(err); <p dir="auto">if we want to catch an error<br /> Cheers!
