R is very much like JavaScript. It's not exactly love at first sight, but it has enough features to make it palatable (vectorization and first-class functions), some wonky parts that can work in your favor if handled with great care (non-standard evaluation and formulas) and you don't really have a choice anyway (CRAN).
