This uses the power of Underscore/Lodash to do a simple swap, assuming we have an array of objects each containing two fields, we want the other field.
var states = [
{'name':'Alabama', 'abbrev':'AL'},
{'name':'Alaska', 'abbrev':'AK'},
{'name':'Arizona', 'abbrev':'AZ'},
{'name':'Arkansas', 'abbrev':'AR'},
{'name':'California', 'abbrev':'CA'},
{'name':'Colorado', 'abbrev':'CO'},
{'name':'Connecticut', 'abbrev':'CT'},
{'name':'Delaware', 'abbrev':'DE'},
{'name':'Florida', 'abbrev':'FL'},

object.is is a polyfill for the es6 egal function: http://wiki.ecmascript.org/doku.php?id=harmony:egal
module.exports = Object.is || function(x, y){
if (x === y) {
// 0 === -0, but they are not identical
return x !== 0 || 1 / x === 1 / y;
}
// NaN !== NaN, but they are identical.
// NaNs are the only non-reflexive value, i.e., if x !== x,
// then x is a NaN.
// isNaN is broken: it converts its argument to number, so
