In JavaScript the default sort order depends on the data types of the variables in question. If either is a string, you convert the other to a string and sort lexicographically, but if both are numbers you compare numerically. There is a similar inconsistency around what the "+" operation does.
Inconsistencies that can arise from string promotion are a common source of surprise.
