That's great, if you frameworks abstractions aren't leaky. Which they almost certainly are.

At that point the question is whether the troubleshooting, as stated, will teach you about how to solve the problem with javascript in general or framework specific contortions to work around it.

Assuming that all frameworks are leaky and writing from scratch is almost always a waste of time. Even if something is leaky and you spend a week trying to fix it, it will probably still be faster to build using those abstractions than to build something from scratch.

In my current company, we were building a multi page form for registration. It took us ( 2 guys ) a whole of 3 weeks ( with html and css pre built! ) to bring it to a level that is acceptable. I had built the same with angular earlier because I was trying to show that it could be done faster and with lesser code. The guys in management did not accept it because it is still "new". So we spent 3 weeks building this which would have taken around 3-5 days in angular.
