I have the source code of a legacy Ionic/Angular project that I’ll need to have migrated to a newer version. In order to do so, I need to figure out which version of Ionic and Angular the code uses. I have the following dependencies in package.json:

"@angular/animations": "5.0.3",
"@angular/common": "5.0.3",
"@angular/compiler": "5.0.3",
"@angular/compiler-cli": "5.0.3",
"@angular/core": "5.0.3",
"@angular/forms": "5.0.3",
"@angular/http": "5.0.3",
"@angular/platform-browser": "5.0.3",
"@angular/platform-browser-dynamic": "5.0.3",
"@angular/platform-server": "5.0.3",
"@ionic-native/android-permissions": "4.5.3",
"@ionic-native/core": "4.5.3",
"@ionic-native/device": "4.5.3",
"@ionic-native/email-composer": "4.5.3",
"@ionic-native/file": "4.5.3",
"@ionic-native/file-opener": "4.5.3",
"@ionic-native/in-app-browser": "4.5.3",
"@ionic-native/keyboard": "4.6.0",
"@ionic-native/screen-orientation": "4.5.3",
"@ionic-native/secure-storage": "4.5.3",
"@ionic-native/sms": "4.5.3",
"@ionic-native/social-sharing": "4.5.3",
"@ionic-native/splash-screen": "4.5.3",
"@ionic-native/status-bar": "4.5.3",
"@ionic-native/unique-device-id": "4.5.3",
"@ionic-native/wheel-selector": "^4.6.0",
"@ionic/pro": "1.0.16",
"@ionic/storage": "2.1.3",
"ionic-angular": "3.9.10",

Does this mean the code uses Angular 5.0.3 and Ionic 4.5.3?
What is “ionic-angular”: “3.9.10”?
