I use the 'ionic serve' and run the app and it does fine on the browser. After editing the app files this tends to happen. It says "FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory'.

I am using ionic 2.1.0 , cordova 6.3.1, node 6.6.0, and npm 3.10.3 on Windows 10 using VS Code.

I attached a screen shot with the problem.
