_From @alexandrudima on January 27, 2016 12:46_ Testing #2218 When I hover over `this.age` in the `console.log` I get to see it is a property of type number, but the assignment in line 2 is not highlighted: ``` javascript function Person() { this.age = 13; } Person.prototype.sayHi = function() { console.log('Hi, I\'m ' + this.age); console.log('Hi, I\'m ' + this.age); } var p1 = new Person(); ```  _Copied from original issue: Microsoft/vscode#2438_
