The DOM is the slowest part of the browser. It's not Javascript, it's the DOM. React is an attempt to manage the slowness of the DOM. One seemingly small change to a page (like setting innerText) can have many ripple effects with reflow on mamy parts of a page.
With thousands of DOM elements on a page, the DOM becomes a bottleneck. This isn't the fault of front-end developers, and it's not really the fault of browser developers. HTML/CSS/JS is a very powerful system, but it's also complex and can cost a lot of compute. When you understand this, then the reasons for React and other front-end frameworks become easier to accept.
You may not need react. If you want to make the smallest possible change to the dom to reduce latency, then make the smallest possible change to the dom. Choose solidjs. (Not a sponsored post).
