I am getting the following error in the browser in Ionic 3 when doing ionic serve.
TypeError: tslib.__spreadArrays is not a function
This is happening after I downgraded to "@ionic/app-scripts": "^3.2.3" from "@ionic/app-scripts": "^3.2.4" because of another error.
I am getting the same error, but using 3.2.4, so my guess is that it is another problem
I upgraded to tslib 1.10 and the error went away (Giving me the next issue to fix)
