I’m broke, and need a job. To get a job, I need demonstrable JavaScript framework experience.

I have most of the technologies I can use demonstrated on my data-driven portfolio site https://money.style, however I don’t use a JavaScript framework.

I’m hoping that the good members of this community would point me in the right direction as to:

Which framework (Angular / Vue / React / Node) is appropriate given the example site?
What stands out as the most obvious place to incorporate a framework?
Would someone be willing to get me started with a code snippet?
I believe once I get started, a framework will make things easier long term. I just need a starting point.

Thanks for your attention, and any replies.

Matt
