Example 1:
Javascript
// Defining underscore contrib variable var _ = require('underscore-contrib');
var sum = _.add( 1, 2, 4, 1 );
console.log("The Sum is : ", sum);
|
Output:
The Sum is : 8
Example 2:
Javascript
// Defining underscore contrib variable var _ = require('underscore-contrib');
var sum = _.add( 1 );
console.log("The Sum is : ", sum);
|
Output:
The Sum is : 1
Example 3:
Javascript
// Defining underscore contrib variable var _ = require('underscore-contrib');
var sum = _.add( 1, 3, 5, 7, 9, 99, 100 );
console.log("The Sum is : ", sum);
