AngularJS vs ReactJS comprision
Pool of available talent
It’s a no-brainer because React has a much larger reach, talent base, and support. For whatever reason ReactJS way of doing things caught on. A lot of people felt that angular was bloated. They were unhappy with breaking changes. The fact that Facebook claims to use ReactJs on their own projects also helped attract talent towards it.
But now, let’s say even if a company wanted to try something like Vue, or Svelte or Stencil, etc., ReactJS will have more talent pool. People learn ReactJS because they think it’s popular amongst corporations and corporations use ReactJS due to the very practical fact that it’s easy to find a ReactJS hire.
ReactJS is very stable
React was first released in 2013, and it seems like it will be around for a while. There aren’t many dramatic modifications, and each update has a smooth update course. Even if the team has changed many things in the internals, the user experience remains very similar. They keep breaking changes to minimal and are relatively easier to adapt to.
No Layout Thrashing due to Virtual DOM
Layout thrashing occurs where a web browser must reflow or repaint a web page several times until it is considered ‘loaded.’ It could take a major hit on performance. Again, Virtual Dom and React isn’t the only solution to this but it seems that it’s the solution people seem to prefer so far.
Declarative programming paradigm could also explain ReactJS’s popularity
Declarative programming is like explaining a scene, while imperative programming is like giving instructions on how to create it. Declarative programming improves the readability and reasonability of code. SQL, CSS, etc are declarative. You don’t tell SQL how to fetch the data, you just declare that you want some data.
Functional programming concepts
There may be simpler alternatives (Svelte, for example), but it’s difficult to match ReactJS’ popularity. The talent pool has grown as a result of the perceived coolness of React. Now it’s big and it’ll take a while to take it down. It’s easier to work with React because it’s older, more mature and you can easily find tooling that makes working with it even easier. Newer frameworks tend not to have that luxury. Hence, ReactJs is here to stay.
