How to make faster scroll effects?

Avoid too many reflows (the browser to recalculate everything)
Use advanced CSS3 for graphic card rendering
Precalculate sizes and positions

Beware of reflows

The reflow appens as many times as there are frames per seconds. It recalculate all positions that change in order to diplay them. Basically, when you scroll you execute a function where you move things between two reflows. But there are functions that triggers reflows such as jQuery offset, scroll... So there are two things to take care about when you dynamically change objects in javascript to avoid too many reflows:

Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

Separate big codebases into multiple repositories.

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

Observable React elements with RxJS

Note: if you want to skip history behind this, and just looking for final result see: rx-react-container

When I just started using RxJS with React, I was subscribing to observables in componentDidMount and disposing subscriptions at componentWillUnmount.

But, soon I realised that it is not fun to do all that subscriptions(that are just updating property in component state) manually, and written mixin for this...

Later I have rewritten it as "high order component" and added possibility to pass also obsarvers that will receive events from component.
