Default Binding

Describing Default Binding

• Default binding occurs when this is the global context
• And this is the global object when a function is invoked without either implicit or explicit binding

• Meaning, it is the global object when we aren't using:

  • A dot
  • The .call() method
  • The .apply() method
  • The .bind() method
• The global context is used depending on where we're working
• In the browser, this will be the window
• In strict mode, the global context is undefined

Illustrating Default Binding

console.log(this);
// Window {parent: Window, opener: null, ...}
