Javascript Interview Questions

[deepanshsingh]

Sir, yha
The count function is called using data[0]("Hey!");. Since the function is called as a method of an array element, the this keyword inside the function will refer to that array element, which is the count function itself.
Inside the count function, this.length will evaluate to the length of the count function, which is 0 (the number of arguments passed to the function).

var ln = 20
function Count(){
console.log(this.ln);
}
const data = [Count, 'A', 0]
data[0]('Hii!')




Now output is "undefined"


Explain where did I make mistake?
