Output:
Curried division is : 4
Example 2:
// Defining underscore contrib variable var _ = require( 'underscore-contrib' );
// Function function sub(a, b, c) {
return a-b-c;
} var curried = _.rcurry3(sub);
console.log( "Curried Subtraction is :" ,
curried(2)(4)(200));

Output:
Curried Subtraction is : 194
Example 3: Reversed Arguments are:
// Defining underscore contrib variable var _ = require( 'underscore-contrib' );
