    My JavaScript recipes

    The code creates a new Promise object and sets its then method to resolve, which will return the result of the code block, and its catch method to reject, which will throw an error if the code block fails.

    Shortcut: promise.full

    return new Promise((resolve, reject) => {
    }).then((result) => {
    }).catch((err) => {
    });
