Loop through arguments and copy every PRoperty of every object passed to the function. And the result will be a new object that has the properties of all the source objects.
function mix() { var arg, prop, child = {}; for (arg = 0; arg < arguments.length; arg += 1) { for (prop in arguments[arg]) { if (arguments[arg].hasOwnProperty(prop)) { child[prop] = arguments[arg][prop]; } } } return child;}var cake = mix({ eggs: 2, large: true}, { butter: 1, salted: true}, { flour: "3 cups"}, { sugar: "sure!"});console.dir(cake);
