Underscore.js _.sub() Method

The _.sub() method returns the difference of all the given arguments.

Syntax:

_.sub( val1, val2, ..., valn );

Parameters: This method returns n values to operate on them.

Return Value: This method returns the difference of all the given arguments.

Example 1: 

Javascript

// Defining underscore contrib variable
var _ = require('underscore-contrib');

var diff  = _.sub( 10, 2, 4, 1 );

console.log("The Difference  is : ", diff);

Output:

The Difference  is :  3

Example 2:

Javascript

// Defining underscore contrib variable
var _ = require('underscore-contrib');

var diff  = _.sub( 10 );

console.log("The Difference  is : ", diff);

Output:

The Difference  is :  10

Example 3:

// Defining underscore contrib variable
var _ = require('underscore-contrib');

var diff  = _.sub( 1, 3, 5, 7, 9, 99, 100 );
