Understanding the sort() function?

var myarray=[7, 40, 300]
myarray.sort() //Array now becomes [300,40,7]

In mathematics, the lexicographic or lexicographical order (also known as lexical order, dictionary order, alphabetical order or lexicographic(al) product) is a generalization of the way the alphabetical order of words is based on the alphabetical order of their component letters.

I don't understand this Three Hundred, Forty, and Seven

How is Seven larger alphabetically shouldn't Three Hundred be larger because it begins with T?

Because it's translating the numbers into character strings for the numbers, not the English words for the numbers. Lexically the character '3' comes before the character '7'.
