Elijah summarized three different methods for dealing with time and dates. The
Finally, the generic method

The deep knowledge of a subject really lies in understanding subtle differences between alternate ways of solving the same problem. How is
nodeName different from
tagName? How are the two increment operators different, e.g.

Writing Clean, Reusable Code
Perf-Track tracks framework performance at scale. It basically tracks the performance in terms of Core Web Vitals for Angular, React, Vue, Polymer, Preact, Ember, Svelte and AMP — on mobile and on desktop. The data set is currently still from 2020, but it gives us some insights into how well sites with these frameworks perform in the wild. For example, React with Gatsby perform better than the ones created with Create React app.
Tim Kadlec also conducted some research around that, comparing jQuery, Vue.js, Angular and React. The end result: the current crop of frameworks isn’t doing enough to prioritize less powerful devices and help to close the gap between desktop and mobile. These figures might give you at least some context to make a more informed decision.
