javascript functions to simulate classes, best practices?

I noticed that i can write functions like the one below to simulate classes. I want to know if this is the most up-to-date way of doing it. Any comments appreciated. Thanks

function Apple(type) {
    this.type = type;
    this.color = "red";
    this.getInfo = function () {
        return this.color + ' ' + this.type + ' apple';
    };
}

var apple = new Apple('testapple');
apple.color = 'blue';
console.log(apple.getInfo());
