Description

Create a new variable called newStory, and set it's value to equal storyText. This is needed so we can create a new random story each time the button is pressed and the function is run. If we made changes directly to storyText, we'd only be able to generate a new story once. Create three new variables called xItem, yItem, and zItem, and make them equal to the result of calling randomValueFromArray() on your three arrays (the result in each case will be a random item out of each array it is called on). For example you can call the function and get it to return one random string out of insertX by writing randomValueFromArray(insertX). Next we want to replace the three placeholders in the newStory string — :insertx:, :inserty:, and :insertz: — with the strings stored in xItem, yItem, and zItem. There is a particular string method that will help you here — in each case, make the call to the method equal to newStory, so each time it is called, newStory is made equal to itself, but with substitutions made. So each time the button is pressed, these placeholders are each replaced with a random silly string. As a further hint, the method in question only replaces the first instance of the substring it finds, so you might need to make one of the calls twice. Inside the first if block, add another string replacement method call to replace the name 'Bob' found in the newStory string with the name variable. In this block we are saying "If a value has been entered into the customName text input, replace Bob in the story with that custom name."
