Question

Object initialization:

var myObject = {};

and

var myObject = new Object();

why the last one is considered an antipattern?

thanks

Answer 1

I’m not sure new Object() really falls under “anti-pattern”, but {} is usually preferred, it’s terse and more flexible at the same time.

When you’re writing JavaScript you want it to end up short…if it can be terse and understandable when writing it as well, as this is:

var myObject = { key: "value" };

…then you get the best of both worlds. Also when you’re creating objects within objects, for example:

var myObject = { subObj: { key: "value" } };

…then you can see it’s much more readable than the alternative new Object() syntax.
