[Solved] Can I get a variables value to use it to bring an array's value.

Question

I want to use my variable to bring an array's output. Like bellow:

var arr = ["A", "B", "C"]
var input = prompt("input");
var output = arr[(instead writing the number of element to get directly, I want here the users input) input]
Please answer my question.

Answer 1

the input by user is stored in a variable called input.

so u would use arr [ input ]

if input is 0 it would mean:
arr [ 0 ]

which is equal to "A"

Answer 2

Thanks a lot!
My code is working correctly now.
