JS Hint - don't make functions within a loop

javascript, jshint

Solution

You can just move the function outside the loop and pass a reference to it to `map`:

function mapCallback(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(mapCallback)
    });
}

Alternatively, you can use a JSHint directive to ignore function expressions inside loops. Just put this at the top of the file in question:

/*jshint loopfunc: true */

Problem

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 : Collection.slice(i, i + 4).map(function(item) { return { id: item[0], title: item[1], }; }) }); } ```
