Advanced Javascript Development Tutorials, Guides & Insights

• Use Primitives over Objects: Prefer using primitive values (like strings and numbers) over objects where possible, as they consume less memory.

  let primitive = 'Hello, world!'; // 16 bytes
  let object = new String('Hello, world!'); // Much more memory

• Encapsulation of private data.
• Reduction of global scope pollution.
• Organized and modular code structure.

The Revealing Module Pattern is a variation of the Module Pattern. It allows you to define all functions and variables in the private scope, and then selectively reveal those you want to be public.
