These posts explains the issue and offer ways to solve it. For a quick answer stick to the first. The second post is the docs of the JS sort() method; it offers valuable information. Google is your friend. https://stackoverflow.com/questions/1063007/how-to-sort-an-array-of-integers-correctly https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort
