Data analysis with JavaScript?

Saturday, May 3, 2014

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).

My focus in JS is mainly data visualization/interaction with the end product of the analysis, so I started studying with this in mind. But I was wondering: is it feasible to do some of the heavy work directly in JavaScript too? Are there JS libraries focused on data analysis (data manipulation with the notion of data frames, implementation of statistical models)?
