I answered several ReactJS questions as best as I could and I gotta tell you, it’s crazy addictive. You are also learning a lot, especially if you actually try to come up with fully working solutions for people’s problems. After playing a little bit with jsbin.com and codepen.io, I opted for using codepen, as it works well and it’s cheaper than jsbin.
Here are some of the pens I created:
* someone asked how to prevent deep linking when going directly to the link: http://codepen.io/alexchiri/pen/GZoRze * an example on how to pass properties to the children component using context: http://codepen.io/alexchiri/pen/WwQVRG * some fun with controlled inputs http://codepen.io/alexchiri/pen/BKjJYj * someone wanted to have access to the redux store from a `onEnter` hook handler: http://codepen.io/alexchiri/pen/yOevGZ * how to access location in route components: http://codepen.io/alexchiri/pen/zqrEBb
These are simply exercises, nothing very complicated, just to illustrate a concept or another with a working example.
Best takeway until now: if you want your answer to be selected, make sure you write a clear, succint, to-the-point answer, that the asker can use right away.
