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

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