Can someone explain me how they are creating a "method" method on an object.
var foo = {};
foo.method = function(name, cb){
this[name] = cb;
};

They're assigning the key method to a function - that's a method. If you're wondering how the key method is used, it's because it's not a reserved keyword in JavaScript.
The actual method creates a new method with the provided name, and sets it to the cb. (This can also be used to make properties, not just methods).
var foo = {};
foo.method = function(name, cb) {
this[name] = cb;
};
foo.method("sayHello", () => console.log("Hello!"));
foo.sayHello();
