Javascript

Notes on the Definitive Guide.

Javascript was created to enable dynamic behavior in the documents displayed by web browsers:

  • A browser is like an OS - they provide a platform for application development and a variety of services like networking, storage, threading, etc.
  • “Client-side” Javascript is code written to run in the browser
  • The JS Web APIs are defined by consensus among browser vendors, and it is written in C++.
  • There are no “official” JS docs - Mozilla Development Network (MDN) is the most authoritative source.
