You don't need to loop in JavaScript (or in most languages actually). There are a couple ways you can accomplish this. Using the [] operator or using the charAt() method. let a = "hello"; a[2] a.charAt(2)

You will have to loop through the string to make sure your target is always on the third character. Example:- var i; var name = "Alex"; for(i = 0; i < name.length, i++) { if(name[2]) { document.write("The third character is " + name[2]); } } I didn't test it but it should give u an idea of what you want
