title: Data analysis with JavaScript?
body: <p>Today my data analysis routine would be something like the following: do the heavy work with either R, Julia or Python and then display it in the web with JavaScript (for example, using D3.js).  </p>
  
  <p>My initial focus with JS was mainly data visualization/interaction with the end product of the analysis, so I started studying it with this in mind. But I was wondering: are there JS libraries focused on data analysis (data manipulation with the notion of data frames, implementation of statistical models) so it would be feasible to do some of the heavy work directly in JavaScript? </p>
