Add AnswerWhat is this?
In JavaScript, the this
keyword refers to an object.
Which object depends on how this
is being invoked (used or called).
The this
keyword refers to different objects depending on how it is used:
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.
Note: this
is not a variable. It is a keyword. You cannot change the value of this
.
