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

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:




// Defining underscore contrib variable
var _ = require('underscore-contrib'); 
  
var mulVal  = _.mul( 8, 22, 10 );
  
console.log("The Product of given values is :", mulVal);

Output:

The Product of given values is : 1760

Example 2:




// Defining underscore contrib variable
var _ = require('underscore-contrib'); 
  
var mulVal  = _.mul( 8 );
  
console.log("The Product of given values is :", mulVal);

Output:

The Product of given values is : 8

Example 3:




// Defining underscore contrib variable
var _ = require('underscore-contrib'); 
  
var mulVal  = _.mul( 0.8, 0.2, 0.9 );
  
console.log("The Product of given values is :", mulVal);

Output:

The Product of given values is : 0.14400000000000004
