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.

How to setup AWS lambda function to talk to the internet and VPC

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.

So it might be really unintuitive at first but lambda functions have three states.

1. No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
2. VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
3. VPC with NAT, The best of both worlds, AWS services and web.
