Why do they use strings as function using to-function (https://github.com/component/to-function https://github.com/component/to-function). Like .select("age>10").map("adress.streetname"); While to-function is cool and your code is shorter and more readable. You must be aware that you miss - static code analysis such as synax checking - compile time optimizations (because the AST is missing) - static code analysis tools - code coverage checking tools I would recommend using real functions, or using clojurescript or coffeescript in order to get shorter code.
