Méthode JavaScript Catch ()

// returns a promise
let countValue = new Promise(function (resolve, reject) {
   reject('Promise rejected'); 
});

// executes when promise is resolved successfully
countValue.then(
    function successValue(result) {
        console.log(result);
    },
 )

// executes if there is an error
.catch(
    function errorValue(result) {
        console.log(result);
    }
);
