Description xracoonx 2014-05-18 07:37:23 UTC 
In the code below the variable 'hasWheels' is marked as being 'unused' in the constructor scope and no hint to the property is produced (e.g. when typing 'redCar.' outside of it).

function Car(color) {
    var hasWheels = true;
    this.color = color;
    this.hasWheels = hasWheels;
}

var redCar = new Car('red');
console.log(redCar.hasWheels);

reproducible in 8.0 and trunk
Comment 2 xracoonx 2014-05-19 20:24:18 UTC 
By the way, this code which I think is equivalent works fine:

function Car(color) {
    var hasWheels = true;
    return {
        color: color,
        hasWheels: hasWheels
    };
}

var redCar = new Car('red');
console.log(redCar.hasWheels);
Comment 3 xracoonx 2014-05-19 21:01:06 UTC 
However, it seems not to create any hints...
