Individual exception catching in promises in JavaScript

In then, you can specify only handler function of an exception by passing null instead of the first parameter:

promise.then(
	null,
	function(error) {
		console.log(error);
	}
);

In this case, it is convenient to use a shortened syntax using the catch method:

promise.catch(
	function(error) {
		console.log(error);
	}
);

Rewrite the following code via the catch method:

let promise = new Promise(function(resolve, reject) {
	setTimeout(function() {
		let isError = false;
		
		if (!isError) {
			resolve('success');
		} else {
			reject(new Error('error'));
		}
	}, 3000);
});

promise.then(
	res => console.log(res),
	err => console.log(err.message),
);
