JavaScript Optimization: Exploring V8 Engine and Hidden Classes for Improved Performance

In JavaScript, Objects are mutable (alterable) data types. Created by literals and compared by reference, JavaScript Objects are the collection of properties, mapping between keys and values.

Performance factor — Property Access Time

Property access mechanism in strongly typed language is different from dynamically typed language. In V8, the object has a hidden class associated with it which works similarly to fixed object layout in Java, except they are created at run time and updated dynamically as object changes.

For more details refer The Secrets of JavaScript Object for Performance Optimization.
