Implement more clojure.core functions

[vickychijwani]

Closer.js currently supports more than 100 functions from clojure.core, but we need to add more to this collection. If someone wants to contribute, feel free to dive in! This is a great place to start contributing. Since we get a lot of free functionality from Mori, many functions become easy to implement.

Steps to add a new function:

• Follow the setup and workflow instructions in the README.
• Decide which function(s) you want to implement. Take a look at which functions are already implemented and what other functions exist in clojure.core. Ignore all special forms and macros for simplicity (feeling adventurous? go ahead! 😄).
• Look at some examples of how the function is used, and add suitable test cases. Try to cover all edge-cases (check implementations and tests of other functions for pointers).
• Look at the actual Clojure source code for that function and figure out how to port it to CoffeeScript / JavaScript (you also have lodash and mori at your disposal!).
• Add your new function to the core library and make your tests pass.
• Send a pull request!

Here's an initial list of missing functions that should be simple to implement (there are many others missing):

• distinct
• rand-nth
• frequencies
• select-keys
• get-in
• assoc-in
• rseq
• not-every?
• not-any?
• distinct?
• vec
• set
• interleave
• interpose

Please leave a comment here stating which functions you're going to tackle before you start working, so others don't end up duplicating your work and vice versa.

This is awesome! Will send a PR soon 😀

@vickychijwani Will I add one PR for every function or consolidate a few?

[vickychijwani]

@koustuvsinha I'm fine with any number of functions per PR as long as they're in separate commits.

Ok. Implemented distinct and rand-nth, now will do the following :

• frequencies
• get-in
• assoc-in

Working on the following :

• not-every?
• not-any?
• distinct?
