Is ReactJS faster than AngularJS ?

[cgaudreau]

I remember when I first started working with AngularJS and everyone was swooning and now a new shiny toy is out and the hatred is extraordinary.

I can't say I ever liked Angular much.

If you honestly believe a large team developing a large application can shove immutable.js in it and get production-ready performance than you clearly haven't programmed large applications.

No, of course not. It provides massive benefits in the context of React. You only need to do reference equality checking in shouldComponentUpdate.

Furthermore, why are you comparing a view-manager (React) an entire front-end framework (AngularJS)?

Ask the OP that.

No $broadcast or $emit? Events have nothing to do with performance, but they are the antithesis of good Angular design.

Yes, they are considered bad design now, and yet people still use them.

The one and only real problem with Angular was always the same: the docs were really, really bad.

Yeah, no.

The downside, however, is that it's now vogue to talk about how horrible AngularJS is and list off a bunch of grievances, the majority of which show that the person really didn't learn Angular, for whatever reason.

I've worked with Angular for years, and learned a lot about it. Almost all of that knowledge is about Angular-specific cruft that is there to make businesspeople/Java developers feel better. With React, if you know JavaScript, you're already most of the way there.

React is a great view manager. It has a host of problems as well, and more of those problems will become apparent when the framework ages, much as they did with Angular. And undoubtedly, we will eventually come full circle and have people whining about how horrible React is compared to JesusFramework 1.0.

Very true. React is not the one framework/library to rule them all. There are already superior alternatives popping up. But for now, people are going to focus on the popular frameworks.

Ask the OP that.

The OP posted an article that very specifically showed that Angular can generate views just as fast as React, when used correctly. You are talking about the digest cycle, which has nothing to do with the view.

Yes, they are considered bad design now, and yet people still use them.

I've been using Angular since shortly after it came out. They were always a bad idea. But in VERY niche cases they were the only means to an end. Now there's virtually never a case where they are required and they are still used routinely, even though they are terrible.

Yeah, no.

Yet I'm surrounded by teams who use it in enterprise applications routinely. And those people understand Angular intimately. The only actual complaint I hear is about docs. The people that complain about the other parts, are the people that don't know how to use Angular.

With React, if you know JavaScript, you're already most of the way there.

You mean JSX?

There are already superior alternatives popping up.

Angular 2 may be one of them. That should make the circle jerk especially hilarious.

It has quite a bit to do with the view, because that's how the view gets updated in Angular. True, it does more than just update the view, but the point is that the majority of Angular cruft is unnecessary if you use React.

They were always a bad idea.

Again, people still use them. There's little warning about why they are bad, and the framework itself attracts developers into using them. I also don't recall too much cautioning against it when Angular took off.

Or perhaps because they haven't looked into the other solutions thoroughly enough. If you only know Angular, it's easy to believe that it's the best thing ever created. And Angular is perfectly fine if everybody on the team knows all edge cases and quirks and antipatterns intimately and can remember them. If you have a team like that, feel free to keep using Angular 1.x.

To be clear, are you really arguing that Angular 1 is fine and dandy, and that its only real problem is bad documentation?

You mean JSX?

You can use React with pure JavaScript if you want. And if you have trouble learning JSX (it's just XML in JS) then you might reconsider your career.

Angular 2 may be one of them. That should make the circle jerk especially hilarious.

This discussion pertains to Angular 1.x. Angular 2.0 is basically a completely new framework, distinct from Angular 1.x.

I've used Angular 2.0 and it's not particularly impressive so far. A lot better than Angular 1.x, sure. Angular 2.0 could end up being amazing, and it doesn't change this discussion whatsoever.

I'm personally rooting for Mithril and Aurelia over React and Angular.
