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 bL = _.bitwiseLeft( 1, 3 ); console.log( "The bitwiseLeft is :" , bL); |
Output:
The bitwiseLeft is : 8
Example 2:
Javascript
// Defining underscore contrib variable var _ = require( 'underscore-contrib' ); var bL = _.bitwiseLeft( 1, 3, 2 ); console.log( "The bitwiseLeft is :" , bL); |
Output:
The bitwiseLeft is : 32
Example 3:
Javascript
// Defining underscore contrib variable var _ = require( 'underscore-contrib' ); var bL = _.bitwiseLeft( 1 ); console.log( "The bitwiseLeft is :" , bL); |
Output:
The bitwiseLeft is : 1
