JavaScript split() method resulting in undefined

I'm working on a simple program that will select a random string from an array. I started with a predefined array, but about halfway through wondered if it wouldn't be simpler (or more elegant) to use a `text file (.txt)`, since I have a bit over 1000 items. I found this solution here (for which I take no credit) and it is working for me... ``` function readTextFile(file) { var items = []; var rawFile = new XMLHttpRequest(); rawFile.open("GET", file, true); rawFile.onreadystatechange = function() { if(rawFile.readyState === 4) { if(rawFile.status === 200 || rawFile.status === 0) { var items = rawFile.responseText.split('\n'); alert(items[0]); } } }; rawFile.send(null); } readTextFile('source.txt'); ``` ...to an extent. I want the `array items[]` to contain one line per item. In other words I want to split per new line. However, all array items are undefiend after `items[0]` when I use `split('\n')`. `items[0]` in the example above becomes the first sentence, so that much is correct. If I want to `alert items[1]` I get undefined. If I use some other split point, such as `split('')`, it works correctly, separating each character per item ONLY until the line breaks, after which point I get undefined again. Let's say the first line of the `.txt is "asd"`: so 'asd' is defined in array as : ``` items[0] = 'a' items[1] = 's' items[2] = 'd' items[3] = undefined ``` This is what I would get. Where am I wrong? Contents of text file: ``` asfe asdasdasd asdasd fgfg ```
