Compilers: Notes from CS-Saturday March 4, 2017

Compilers and Parsing

Your program is also a piece of data!

How Humans Read

We learn through practice and exposure. We don't study grammar till much later in life. We break down a sentence into a sequence of words.

  1. Lexing (to tokens)
  2. Parsing (grammar)
  3. Semantic Analysis

Understanding Binding and 'this' in Javascript by zach.dev

How to Eyeball Your ‘This’ Context in Javascript

by zach.dev

The early programmer struggles with the Javascript keyword this. But understanding your this context is easier than it seems.

This is all about where a function is invoked. Often, early programmers worry about where the function was declared. Perhaps the function was declared in a specific file or a particular object. Surely this changes it's this!

Nope.

Express.js – A Gentle Overview

Express.js – A Gentle Overview

Zach Caceres

Express.js is a Javascript library that handles web routing and HTTP requests for web applications.

Express builds on the native HTTP library in node.js to allow for a simple, object-oriented approach to routing your web application.

The creators of Express.js describe it as a 'minimalist framework', meaning that Express.js handles a few core tasks well, but does not include many nice-to-have features. Instead, you can enhance your Express.js application with middleware downloaded from npm or that you build yourself.

This series has four parts.
