I'm an Angular developer facing a fresh project in the finance sector, particularly stock trading, where I have the freedom to select the frontend technology. My main concern isn't the initial setup but rather how well the framework performs on the client-side, especially since we expect to deal with thousands of real-time quotes through WebSocket connections. I recognize that both Angular and React can handle these loads, but I've heard conflicting opinions about performance, specifically regarding React being faster. Has anyone been in a similar situation? What are your thoughts on the performance of Angular versus React (or other frameworks) for handling high-frequency data visualization? How would you go about making this decision?

I've been in your shoes, and from experience, if you’re looking at high-frequency data visualization, both Angular and React are capable but have their nuances. Angular does shine for larger applications due to its structured nature, while React allows more fine-tuning for performance. If you have a skilled team comfortable with either, their familiarity will greatly affect your decision.
It's true that both React and Angular can manage high-frequency updates, but some argue that React tends to offer better performance with clever hooks and state management techniques. On the flip side, Angular has made strides in fine-grained reactivity lately. If performance is core to your app, that might sway you.
If you're already comfortable with Angular, I'd say stick with it. Both frameworks have solid performance, but since you know Angular, that might give you an edge in development speed. Plus, Angular can handle enterprise-level applications really well, especially for complex scenarios like yours.
I haven't worked with Angular much, but for performance, you might want to check out SolidJS or Svelte. They're known for snappy performance with high-frequency updates. Also, Angular's recent updates with signals could give you significant improvements in reactivity!
When dealing with real-time data, a lot depends on how you manage updates in your app. Both frameworks can handle WebSockets well. That being said, if you're seeking extremely responsive UIs, I'd lean towards React for better control over rendering, especially when using hooks for optimizations.
Right, it boils down to the team's knowledge. If your team is used to C#, they'll likely mesh well with Angular. React has its perks for fast updates, but that requires some tinkering.
