I am a total newbie and currently learning Javacript. I encountered this problem on JSChallenger and have been struggling with it. Here's my code:
// Write a function that takes a string (a) and a number (n) as argument
// Return the nth character of 'a'
function myFunction(a, n)
{let string = a;
let index = n;
return string.charAt(index);
}
Can anyone point out my errors? Thanks so much!
Try this one
function myFunction(a, n){
return a[n - 1];}
// there is a shorter way to do this since you want to find what's missing here is what's missing.
function myFunction(a, n){
let string = a;
let index = n-1;
return string.charAt(index);
}
JS string's index starts enumerating from 0 so the n should be decremented by 1
// Write a function that takes a string (a) and a number (n) as argument
// Return the nth character of 'a'
function myFunction(a, n)
{
let string = a;
let index = n;
return string.charAt(index-1);
}
the easiest way to write it would be:
// Write a function that takes a string (a) and a number (n) as argument
// Return the nth character of 'a'
function myFunction(a,n) {
return a[n - 1];
}
Meaning return from string "a" of myFunction the index "[n-1]" , "n-1" it's a needed operation to get the right index because string index start enumerating from 0.
