JS Hint - don't make functions within a loop

Question

I can not get around JSHint\'s error message. Here is the loop I am using:

for (i = 0; i < Collection.length; i += 4) {
    data.push({
        items : Co

Declaring a function in a loop is messy, and potentially error prone. Instead, define the function once, and then enter the loop.

var objMaker = function(item) {
    return {
        id : item[0],
        title : item[1],
    };
};

for (i = 0; i < Collection.length; i += 4) {
    data.push({
                  items : Collection.slice(i, i + 4).map(objMaker)
             });
}
