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.
Note: This will not work in normal JavaScript because it requires the underscore.js contrib library to be installed. Underscore.js contrib library can be installed using npm install underscore-contrib –save.
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:
Javascript
// Defining underscore contrib variable var _ = require('underscore-contrib');
var diff = _.sub( 1, 3, 5, 7, 9, 99, 100 );
console.log("The Difference is : ", diff);
|
Output:
The Difference is : -222
