Based on my understanding of javascript, prototype methods cannot access variables that are private to the scope of the constructor,
This question already has answers here: Javascript object members that are prototyped as arrays become shared by all class instances
I\'ve used a few tutorials on OOP in JavaScript. It seemed to go well, until I met the following... Result of expression \'this.prepareFrame\' [undefined] is not a function.
I would like to extend the Boolean object with a prototype function that inverts it\'s current value. Until now, I\'ve been doing something like this:
Could someone explain this to me in a sensible way: function One() {} One.prototype.obj = { key: \'value\' };
I\'m trying to understand the \"JavaScript way\" of creating and using objects and I think I\'m running into a misunderstanding of an object and a prototype.
Using pure JavaScript to do inheritance, this is what I usually do: function A() {} A.prototype.run = function () {};
I have a problem with inheritance of two functions in node.js when i use require functions. Here is my case:
Here is an object: var obj = new function(){ this.prop = {}; } and I try to do something like: obj.prop.prototype[\"new_attr\"] = \"some_value\";
I\'m reading this book and there is a chapter about prototypes with this hard to understand paragraph and code snippet.
