My attempt at the code challenge.

How could I capitalise the first letter of the pronouns without capitalising the other letters in the string?

alert('Welcome to Consequences, a series of questions will be posed and Consequences will adapt your answers into a story. Give it a try.');
var him = prompt('What was his name?');
console.log(him);
var her = prompt('What was her name?');
console.log(her);
var place = prompt('Where did they go?');
console.log(place);
var what = prompt('What did they do?');
console.log(what);
var heSaid = prompt('What did he say?');
console.log(heSaid);
var sheSaid = prompt('What did she say?');
console.log(sheSaid);
var happenings = prompt('What happened?');
var story = (him + " & " + her + " went " + place + " on a date. " + him + ' said "' + heSaid + '". ' + her + ' said "' + sheSaid + '". ' + happenings + ".");
document.write(story);

Hi Adam,

You can use a function like this one:

function capitalizeFirstLetter(string) {
    return string.charAt(0).toUpperCase() + string.slice(1);
}

Then you can call it in each prompt:

var him = capitalizeFirstLetter(prompt('What was his name?'));

Another way you can implement this to make it even clearer is by assigning the function to the __proto__ of the String object as you can see below.

String.prototype.capitalizeFirstLetter = function() {
    return this.charAt(0).toUpperCase() + this.slice(1);
};

alert('testing'.capitalizeFirstLetter());

Of course this is a little more advanced but it provides more context than a function.

First off, thank you Hugo Paz and secondly Chris thanks for the reply. This is all a little beyond me at the moment, but I will be sure to revisit once I have covered some more JavaScript.

Many thanks to you both!
