Javascript and Inheritance

Objects

  • Objects in Javascript are essentially hashes.
  • There are special types of objects such as strings, integers, and functions, but a 'plain Javascript object' is just a hash consisting of key-value pairs.
  • Keys must be strings. Values can be any object, including functions.

Prototypes

  • Every object has a 'prototype' that it inherits from.
  • Prototypes are simply objects containing various properties.
  • When you call a property of an object, Javascript first looks inside the object to retrieve that property. If it doesn't find it, it looks inside the object's prototype.
  • You can only set an object's prototype once; it can never be overwritten.
