Question

Let arr = arr[1,2,3,4];
alert(arr[arr[1]);
To find the index you count from zero... but the answer is 3, why???🤔🤔🤔🤔

Answer 1

arr[1] is the second element of the array, so it will be 2. arr[2] will be this third element, so it will be 3

Answer 2

Airree exactly what i got, but when i ran the code through the console it gave me 3😳

Answer 3

Airree the arr[arr[1]]. i wonder the first arr[], automatically takes 0 position as the starting position that does make sense and then when the next arr is nested marks the ending position - arr[arr[1]] ... doea not make sense .....
but thats alot for helping me work this out 😊😊

Answer 4

Yeah, the result is 3
