how to end ng serve or firebase serve

Question

I\'ve been doing web development with Angular2 and have been using both Angular2 and Firebase to run local servers. I haven\'t been able to find a command similar to typing quit

Answer 1

With Windows 10 / Powershell ctrl + c did not work; Powershell tried to gracefully stop the app.

Used normal cmd and had no issues stopping the ng serve with ctrl + c.
