What would you like to do?
Simple function to detect type Array. JavaScript return type "object" whether you give it an actual object like { red:44, green:57, blue:220 }, or an array like [44, 57, 220]. So I wrote this small function to separate the two.
function istype(obj) {
return (typeof obj !== 'object' || typeof obj[0] === 'undefined')
? typeof obj
: 'array';
