Something I stumbled upon for method chaining...along the lines of an Expression Builder, but without a named object.

chaining.js

//So, I came up with this when playing with an idea for a configuration DSL. It's like Expression Builders...I think.
//I think it's really like Partial Application with named functions.
//But is it rubbish?
//This is a contrived example for addition
var add = function(x){
  //Right here is the basic pattern.
  //Rather than return a function, return and object with a named function so your chaining becomes more grammatical
  return{
    to: function(y){
      return x + y;
    }
  };
}

//which let's me write this
var result = add(10).to(20) //==> 30;

//or
var add10 = add(10);
var result = add10.to(20) //==> 30;

//Like I said, it's a stupid example, but the idea is ther.
