Is there a way to get a certain letter from a value inside of an array?
For example, if my array is:
const names = ['john', 'james']
Is there a way to get the 2nd letter in 'john' using code?

You can use the subscript operator ([]) to get a specific element of the array. Then, you can use the subscript operator again to get a specific character from a string:
const result = names[0][1];
Note that both array indexes and string indexes are zero-based.

function myFunction() {
var names = ["John", "james", "jacky", "man"];
var result = names[0][1];
document.getElementById("demo").innerHTML = result;
}<button onclick="myFunction()">Try it</button>
<p id="demo"></p>

It's also possible to use the substring function.
const names = ['john', 'james'];
//substr(<where to start>, <length of string>)
var letter = names[0].substr(1, 1);
