JS: Create Object

By Xah Lee. Date: . Last updated: .

There are 3 ways to create a data object.

  1. Literal expression: {…} → Most useful, when you want to use it as a set of key/value pairs for data.
  2. Object.create() → Most powerful and flexible way to create object, because you can specify parent object, properties, property attributes, in one place.
  3. Keyword new, in new function_name() → complex behavior. Most useful when you are writing a object-oriented library.
