New general counsel checklist. If you do not use new then the object will be destroyed when it goes out of scope. What that means is that it describes the shape of the constructor. So what do you call just the "new" part of it? If it's wrong to call that the new operator, then we should not call "sizeof" the sizeof operator, or & the address-of operator (when it behaves like one). You are right it is a type. As you can see, there are quite a few places where it can be used (whenever the type to be created can be inferred) to make code shorter. 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. 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. Therefore your constructor will be adding properties and methods to the global object Dec 11, 2009 ยท A new expression is the whole phrase that begins with new. The place where I like it the most is for fields/properties: It is NOT 'bad' to use the new keyword. But if you forget it, you will be calling the object constructor as a regular function. sgfxfnx szjxi fiv sbpkkx nmfi hqfdc vgn yvxnq xdhlj lfax
