Lodash _.isEqual() Method

Lodash _.isEqual() Method performs a deep comparison between two values to determine if they are equivalent. This method supports comparing arrays, array buffers, boolean, date objects, maps, numbers, objects, regex, sets, strings, symbols, and typed arrays. 

Syntax:

_.isEqual( value1, value2);

Parameters:

• value1: First comparable value
• value2: Second comparable value

Return Value:

• This method returns a Boolean value(Returns true if the two values are equal, else false).

Note: Objects are compared directly, their inherited or enumerable properties are not compared. Functions and DOM nodes are compared strictly by the '===' operator.

Example 1: In this example, We are comparing two variables having objects as a value and printing results in the console.

// Defining Lodash variable 
const _ = require('lodash');

// First value
let val1 = { "a": "gfg" };

// Second value
let val2 = { "b": "gfg" };

// Checking for Equal Value 
console.log("The Values are Equal : "
    + _.isEqual(val1, val2));

Output:

The Values are Equal : false

Example 2: In this example, We are comparing two variables having Array as a value and printing results in the console.

// Defining Lodash variable 
const _ = require('lodash');

let val1 = [1, 2, 3, 4]

let val2 = [1, 2, 3, 4]

// Checking for Equal Value 
console.log("The Values are Equal : "
    + _.isEqual(val1, val2));

Output:

The Values are Equal : true

Example 3: In this example, We are comparing two variables having String as a value and printing results in the console.

// Defining Lodash variable 
const _ = require('lodash'); 

let val1 = "gfg"

let val2 = "gfg"

// Checking for Equal Value 
console.log("The Values are Equal : "
        +_.isEqual(val1,val2));

Output:

The Values are Equal : true

Example 4: In this example, We are comparing two variables having Numbers as a value and printing results in the console.

// Defining Lodash variable 
const _ = require('lodash');

let val1 = 1

let val2 = 1

// Checking for Equal Value 
console.log("The Values are Equal : "
    + _.isEqual(val1, val2));

Output:

The Values are Equal : true
