• Hoisting

  • Explain Hoisting in JavaScript
  • Why Hoisting Important?
  • First, memory is set aside for all necessary variables and declared functions
  • Function Expressions are never hoisted! They are treated as assignments
  • Check if return statement is at the top
  • Analyzing Hoisting Load Order I
  • Analyzing load order II
  • Analyzing Load Order III

• Prototypes and Inheritance

  • Prototypes!

  • Discuss: __proto__, [[Prototype]], prototype
  • Two mechanism always exists in JavaScirpt -- Lexical Scopes & Prototype Chain
  • Object Oriented in JavaScript
  • Explanation of Prototype
  • When an inherited function is executed, the value of this points to the inheriting object, not to the prototype object where the function is an own property
  • New object using Object.create() (ES5)
  • New object using class syntactical sugar
  • Similar in Object pattern
  • Use hasOwnProperty() to know if the property exists as it's own property
  • Prototype shadowing
  • Avoid Shadowing
