title: Angular6 What's browserTarget
body: <p>Here is a standard angular.json file </p>
  
  <pre><code>"projects": {
    "myApp": {
       [...]
       "architect": {
         "build": {
           [...]
           "configurations": {
             "production": { [...] },
             "debug": { [...] }
           }
         },
         "serve": {
           [...]
           "configurations": {
             "production": {
               "browserTarget": "myApp:build:production"
             },
             "debug": {
               "browserTarget": "myApp:build:debug"
             }
           }
         }
       }
     }
   }

  <p>I don't understand what's the <code>browserTarget</code> setting for ?
  I couldn't find any documentation, it seems that I'd have to dig into <code>@angular-devkit</code> ...</p>
