                A subtle introduction to Lambda Calculus for the JavaScript Developer
              
          
    Lambda (λ) Calculus For Javascript Developers

This article aims at explaining lambda calculus in a more approachable less 'mathy' manner.
Terms That Are Good To Know


Memoization: Memoization is an optimization technique used primarily to speed up computer programs by caching the result of expensive function calls and returning the cached result when fed with the same input.


Pure Function: A pure function is a function whose computation does not depend on globally declared variables, it does no I/O or mutations. All it does is return a value after doing a bunch of computations on the arguments it recieves. For a given set of arguments, a pure function will always return the same value. Thus, a pure function is one that is memoizable.

    Configuring Emacs for react, es6, and flow

For a while, JSX and new es6 syntax had flaky support in emacs, but there's been huge work on a lot of packages. Using emacs for JavaScript with React, ES6, and Flow (or Typescript, etc) is really easy and powerful in Emacs these days.
This is how you can work on modern web development projects with full support for tooling like JSX, Flow types, live eslint errors, automatic prettier.js formatting, and more.
Set up web-mode

web-mode provides most of the underlying functionality, so a huge shout-out to the maintainer(s) there.
