This lesson

This lesson teaches Route params: the concepts, APIs, and habits you need before advancing in AngularJS.

Routing maps URLs to components—guards and resolvers protect enterprise flows.

You will apply Route params in contexts like: Legacy SPAs with ngRoute and templateUrl partials in enterprise intranets.

Write JavaScript for AngularJS 1.8, click Run—register modules/controllers, then mountApp(moduleName, templateHtml) in #ng-app; printOutput feeds the terminal.

When you can explain the previous lesson's ideas without copying starter code.

$routeParams reads :id segments from the active route for detail views.

Include 'ngRoute' in your module dependency array—the playground CDN loads angular-route.min.js.
