mal - mal - Make a Lisp

•    Assembly

Mal is a Clojure inspired Lisp interpreter.Mal is a learning tool. See the make-a-lisp process guide. Each implementation of mal is separated into 11 incremental, self-contained (and testable) steps that demonstrate core concepts of Lisp. The last step is capable of self-hosting (running the mal implementation of mal).

ES6-for-humans - A kickstarter guide to writing ES6.

let allows you to create declarations which are bound to any block, called block scoping. Instead of using var, which provides function scope, it is recommended to use block scoped variables (let or const) in ES6. Arrow functions are a short-hand notation for writing functions in ES6. The arrow function definition consists of a parameter list ( ... ), followed by the => marker and a function body. For single-argument functions, the parentheses may be omitted.
