safe.js

var transforms = [
	Promise.resolve(1), 
	Promise.resolve(2), 
	Promise.reject(3),
	new Promise((resolve, reject) => { throw "Oops" }) // uncaught 
	Promise.resolve(5)
];		

Promise.all(transforms.map((p) => {
	return p.catch((err) => {
  		console.log('error', err);
		return 'x';
  	});
})).then(a => console.log(a)); // yields [1, 2, "x", "x", "x", 5]
