Underscore.js _.bitwiseAnd() Method

The _.bitwiseAnd() method returns the result of using the Bitwise & operator on all the arguments.

Syntax:

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

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

Return Value: This method returns the result of using the Bitwise & operator on all the 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 bA  = _.bitwiseAnd( 1, 3 );

console.log("The bitwiseAnd is :", bA);

Output:

The bitwiseAnd is : 1

Example 2:

Javascript

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

var bA  = _.bitwiseAnd( 1, 3, 4, 6 );

console.log("The bitwiseAnd is :", bA);

Output:

The bitwiseAnd is : 0

Example 3:

Javascript

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

var bA  = _.bitwiseAnd( 1 );

console.log("The bitwiseAnd is :", bA);

Output:

The bitwiseAnd is : 1
