platform-browser VS platform-browser-dynamic

In angular2. We must have seen in every project there is plugin called platform-browser and platform-browser-dynamic.

 "@angular/platform-browser": "2.0.0-rc.4",
 "@angular/platform-browser-dynamic": "2.0.0-rc.4",
  

Let us understand the difference.

The difference between platform-browser-dynamic and platform-browser is the way your angular app will be compiled.

@angular/platform-browser

• It contains code shared for browser execution (DOM thread, WebWorker)
• Ahead-of-Time pre-compiled version of application being sent to the browser. Which usually means a significantly smaller package being sent to the browser.

@angular/platform-browser-dynamic

• It contains the client side code that processes templates (bindings, components, ...) and reflective dependency injection.
• Uses Just-in-Time compiler and make's application compile on client-side.

When the offline template compiler is used, platform-browser-dynamic isn't necessary because all reflective access and metadata are converted to generated code.
