Function
JavaScript functions are objects. They can be defined using the Function constructor, like so:
var sum = new Function('a', 'b', 'return a + b;');
This is a (generally not recommended) alternative to the function literal (also known as function expression):
var sum = function (a, b) {
return a + b;
};
Or, the more common function definition:
function sum(a, b) {
return a + b;
}
