I'm sure this is really simple but I am learning Javascript and I can't figure this out.
var niceDay = "please, have a nice day";
- How do I create an array using "niceDay", and output the array?
- how do I output the item in index 2?!

Match the non-whitespace:
niceday.match(/\S+/g);
You can use the 'split' javascript function. This will split a string on a certain character and return an array:
var array = niceDay.split(' ');
This will return an array split on each space in the string. You can then access the second item in the array using:
var item = array[1];
Or assign the second item a new value using:
array[1] = 'string';

Thank you for your help Judder! Silly question about my 2nd question thou…I want to make sure I'm on the same page. Once I use split() for my array, to get index[2] in niceDay, would I say niceDay[2];? Would the word 'have' then display?

A javascript array index is zero based meaning it starts at zero so in order to get the second item ('have') you would need to use array[1] in the array you returned from the split method. Array[2] would return the third item ('a')
Well this should be simple, that's true
Here's a solution
var niceDay = "please, have a nice day";
var niceDarray = niceDay.split(' '); // splits the string on spaces
// alerts each item of the array
for (var i = 0; i < niceDarray.length; i++) {
alert(niceDarray[i]);
}
