What's the best framework out there today? I heard Ember has a good learning curve. But wait, Angular is backed by Google so it should be good. Facebook built React and it follows FP and Flux, so its better. What can you say?
I hear this quite a lot on the internet and in the workplace. People ask me what's the best and easiest framework out there. Long story short, I just tell them "None. It depends on your application and methodology.". There are tradeoffs for each framework. However, one should not spend 1 month deciding and testing a bunch of frameworks. Just get one you're comfortable building with and just build.
I'd say, just pick one up and go. If you're an ORM guy or an OOP guy, then Ember or Backbone are your cards. If you're the FP guy or comes from a game dev background, React would be your weapon of choice. Fancy two-way binding and quick component design, then choose among Angular, Ractive, Knockout or Polymer.
People have been moving from RequireJS to Browserify because RequireJS gives you configuration headache. But there's a new kid in town called Webpack which allows you to write AMD, CJS and [insert more acronyms here].
Now for advanced developers, these deficiencies are the things they'd want to avoid. They start to encapsulate code, split them off to logical parts, have those logical parts talk to each other, and presto! We declare that we need package managers... but JS doesn't have one. So we then look for one, and presto, we get a whole lot of choices from RequireJS to Browserify and even eccentric ones like Webpack.
RequireJS wins hands down for me because you don't need an uber-difficult setup. You don't need to download Node, or install some package, nor run some watcher that compiles shit. RequireJS, admittedly is a hack, but it's a good hack nevertheless. Gets you started quick and easy, though configuration might need a little learning.
I have done my share of argument working with people who...
This doesn't work in IE8 and below
This is ES5 things, this won't work in older browsers
This is HTML5 and CSS3
IE still takes a good 20% of the browser market
Let's take the last statement as benchmark. Sure, IE takes up a good 20% the last time I heard. However, how much of the 20% are actually IE8 and below? 4%? 2%? The last time I checked, IE9 was good enough to be called a "modern browser", IE10 and later were astoundingly awesome.
Around another good 40-70% is owned by Chrome and Firefox, which have been doing modern shit since I was still learning JS. I wouldn't worry as much for these guys, they always have it. Since Opera moved to Blink, and Safari is just Webkit (thus they are Chrome-like in a way), then I could just shrug and say I don't care, coz browsers are good enough.
So stop this argument, it's nonsense. You're arguing for support for 4% of the world. What are the chances that you'll meet someone in 2015 using IE6? Give me some analytics then I'll reconsider. Otherwise, I'll pass on doing an extra 2 weeks of work for supporting legacy IE.
