Last weekend I finished converting the FX calculator I developed during my career break to React.js. I have briefly touched some code at work but I wanted to get my hands dirty and understand better the advantages and the challenges of this library.

I was also checking today some interesting [Google Trends data](https://t.co/aCOxxTOhUo) about the most popular JavaScript frameworks in terms of search interest, and React is definitively winning the interest war.
