Hello there, have a look at the "String Methods" part in Day 2.
Let's access the fourth character in 'JavaScript' string for example.

let string = 'JavaScript'
let fourthLetter = string[3]
console.log(fourthLetter) // a

or maybe just string.charAt(random number)

can u plz check my answer:

*/

const accessStr = 'JavaScript'
lastIndex = accessStr.length - 1
console.log(lastIndex)
randomNumToAccess = Math.ceil(Math.random() * lastIndex)
console.log(randomNumToAccess)
console.log(accessStr.charAt(randomNumToAccess))

I think it works.
Maybe just the question made us a bit confusing.
You can type a random num yourself either.

let string = 'JavaScript'
console.log(string.charAt(random number))

//random number = 0~9

My Solution

const JS = "JavaScript";
console.log(JS[Math.floor(Math.random() * (JS.length - 0 + 1))]);

We can utilize Math.random() to generate random number and multiply it with String.length so that the resulting number matches the length of the String.

My answer is like this:

const str = 'JavaScript';

console.log(str[Math.floor(Math.random() * str.length)]);
