Javascript Deep Dive

This document is written to help JavaScript developers to understand JavaScript's weird parts deeply and to prepare for interviews, the following resources was really helpful to write this document:

• ECMAScript 6 Language specification
• ECMAScript 5 Language specification
• MDN
• The Modern JavaScript Tutorial

General Notes

DOM Performance

• How the browser renders the document
  • Receives the data (bytes) from the server.
  • Parses and converts into tokens (<, TagName, Attribute, AttributeValue, >).
  • Turns tokens into nodes.
  • Turns nodes into the DOM tree.
• Builds CSSOM tree from the css rules.

Under Terminal > Preferences... > (Profile) > Advanced, "Declare terminal as:" should be set to xterm-256color.

2. Build a version of screen that supports 256 colors

This is easy with homebrew:

brew install screen
