The value of the this
keyword is dependent on where you use it. In a method, like the getStatus
method, the this
keyword refers to the object that the method belongs to. The method belongs to the data
object, so this
refers to the data
object. When we log this.status
, the status
property on the data
object gets logged, which is ""
.
With the call
method, we can change the object to which the this
keyword refers. In functions, the this
keyword refers to the the object that the function belongs to. We declared the setTimeout
function on the global object, so within the setTimeout
function, the this
keyword refers to the global object. On the global object, there is a variable called status with the value of ""
. When logging this.status
, ""
gets logged.
