Marks the control and all its descendant controls as touched. AbstractControl - Get docs strongloop The above comparison criteria showcases that Angular fights tough against react on small scale apps. It is not possible to make leaps without updating to the consecutive versions. At this point, switching to another technology would be too costly and timeconsuming, so rest assured that Angular will stay with us for long.
