Updating first letter to uppercase using .substr

Question

im attempting to update the first letter of a string to upper case, Please note that im only allowed to use .substr and .length to convert it. no regex or anything.

is this the right method/syntax to do so?

e1 = prompt("Please enter your first name", "andrew");

e1.toUpperCase(e1.substr(e1.length - e1.length,0));

You can really use google for this kind of stuff. It's pretty general — php_nub_qq, Mar 18 '15 at 21:16

Regex everything!

e1 = prompt("Please enter your first name", "andrew");
e1.replace(/^\w/, function(t){ return t.toUpperCase() })

@AndrewBarsoom `e1 = e1.substr(0,1).toUpperCase() + e1.substr(1);` – php_nub_qq Mar 18 '15 at 21:23
