Modernizing Object Creation

ES6 introduced several syntactical sugars for defining object literals, making code more concise and expressive. These enhancements are particularly useful in factory functions and state management.

1. Property Shorthand

If a variable name matches the property key, you can omit the value.

2. Method Definitions

You no longer need the function keyword to define methods on objects.

3. Computed Property Names

You can use an expression inside square brackets [] to use a dynamic value as a property key directly inside the object literal.
