intArr.length function shouldn't br intArr.length();

Answer 1

for array it's .length. for string it's .length ()

Answer 2

array is not an object so a method won't work that's why we have .length, a string is an object so we need a method => .length ()

Answer 3

why so ?

Answer 4

oohh yes
I knew about string as a class but not array
thanks
