This Keyword

In JavaScript, the this keyword is a little different compared to other languages. It refers to an object, but it depends on how or where it is being invoked. It also has some differences between strict mode and non-strict mode.

  • In an object method, this refers to the object
  • Alone, this refers to the global object
  • In a function, this refers to the global object
  • In a function, in strict mode, this is undefined
  • In an event, this refers to the element that received the event
  • Methods like call(), apply(), and bind() can refer this to any object
