JS: Create Object

By Xah Lee. Date: . Last updated: .

There are 3 common ways to create data object.

Object Literal Expression

Most useful, when you want to use it as a set of (key and value) pairs for data.

Object.create()

Most powerful and flexible way to create object, because you can specify parent object, properties, property attributes, all in one function call.

Create Object by new (operator)

complex behavior. It tries to be similar to Java's object oriented programing concepts, but the result is very complex. For some standard objects, such as Date, it's the only way to create it.

Note: remember that function and array are also objects. So, when you define a function or create a array , you are also creating objects.
