New logitech x56, You should use new when you wish an object to remain in existence until you delete it. It is the type of a class whose constructor takes in no arguments. The place where I like it the most is for fields/properties: Jul 11, 2013 ยท Note that if you declared it var a = new { }; and var o = new object();, then there is one difference, former is assignable only to another similar anonymous object, while latter being object, it can be assigned to anything. If you do not use new then the object will be destroyed when it goes out of scope. The new keyword in JavaScript can be quite confusing when it is first encountered, as people tend to think that JavaScript is not an object-oriented programming language. You are right it is a type. If your constructor doesn't check its execution context then it won't notice that 'this' points to different object (ordinarily the global object) instead of the new instance. prototype is used instead. The new keyword in JavaScript can be quite confusing when it is first encountered, as people tend to think that JavaScript is not an object-oriented programming language. For instance take {new(): T; }.
