How to sort an array of structs in ColdFusion

Question

I have an array of structs in ColdFusion. I\'d like to sort this array based on one of the attributes in the structs. How can I achieve this? I\'ve found the StructSort fun

You can use the Underscore.cfc library to accomplish what you want:

arrayOfStructs = [
    {myAttribute: 10},
    {myAttribute: 30},
    {myAttribute: 20}
];

_ = new Underscore();

sortedArray = _.sortBy(arrayOfStructs, function (struct) {
    return struct.myAttribute;
});

Underscore.cfc allows you to define a custom comparator and delegates to arraySort(). You can use it for sorting arrays, structs, queries, or string lists, but it always returns an array.

(Disclaimer: I wrote Underscore.cfc)
