As told in the Douglas JavaScript good parts, I tried to create a array method as below,
Array.method('reduce', function (f, value) {
});
but I am getting
Uncaught TypeError: Array.method is not a function at :1:7

There is no method() in the Array.
In Douglas Crockford's posts, he have created that method himself and then uses it.
This is the code
Object.prototype.method = function (name, func) {
this.prototype[name] = func;
return this;
};

You need to read the section titled "A Simple Testing Ground" on page 20:
Throughout the book, a method method is used to define new methods. This is its definition:
Function.prototype.method = function (name, func) { this.prototype[name] = func; return this; };It will be explained in Chapter 4.
