JavaScript Enumeration object - faster with strings, or numbers? -

-

in project working on, have script 'enumeration' object in it, such:

var myenumeration = {     top: "top",     right: "right",     bottom: "bottom",     left: "left" };

when have use use 1 of literal values, comparison myenumeration.left or whatever case is.

however: @ least in c#, string values evaluate more numbers, since strings have character-for-character comparision ensure string matches string b.

this brings me question: implementing myenumeration number values perform more quickly?

var myenumeration = {     top: 0,     right: 1,     bottom: 2,     left: 3 };

when comparing strings, javascript compares each characters 1 one, left-to-right. when comparing 2 numbers, it's single comparison. can guess 1 faster - numerical comparison.

however, kind of optimization might premature. unless need efficiency gain (comparing hundreds of values frequently, perhaps?), don't think them.
