The _.eq() method compares the arguments with loose equality (==).

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

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

Return Value: This method returns a boolean (true if arguments are equal else false).

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 equal  = _.eq( 1, "1" );

console.log("The Given values are equal :",equal);

Output:

The Given values are equal : true

Example 2:

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


var equal  = _.eq( "Geeks", "Geeks" );

console.log("The Given values are equal :",equal);

Output:

The Given values are equal : true

Example 3: A valid value returns true hence on comparing with true boolean, the comparison returns true.

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


var equal  = _.eq( 1, true );

console.log("The Given values are equal :",equal);

Output:

The Given values are equal : true

Example 4: A valid value returns true hence on comparing with false boolean, the comparison returns false.

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


var equal  = _.eq( 1, false );

console.log("The Given values are equal :",equal);

Output:

The Given values are equal : false
