JavaScript array split at odd index

Question

I have an array of products this contains a product name and a manufacturer, e.g. "product","manufacturer","product","manufacturer" etc..

How can I spilt the array into a separate array so that I can have the products and manufacturers in separate arrays? I want to spilt it at every odd index so that I can take the manufacture out of the array and add this into a new array?

Thanks.

Answer 1

/**
 * @param candid Array of results
 * @return Returns an array where index 0 = array of even ones, and index 1 = array of odd ones
*/
function splitArray(candid) {
    var oddOnes = [],
        evenOnes = [];
    for(var i=0; i<candid.length; i++)
        (i % 2 == 0 ? evenOnes : oddOnes).push(candid[i]);
    return [evenOnes, oddOnes];
}

Try with something like this:

var arr = ["product","manufacturer","product","manufacturer"];
var products = [];
var manufacturers = [];
for (var i = 0; i < arr.length; i += 2) {
    products.push(arr[i]);
    arr[i+1] && manufacturers.push(arr[i + 1]);
}
