Lodash _.entries() Method

The _.entries() method is used to create an array of keyed-value pairs for the specified object. If object is a map or set, its entries are returned.

Syntax:

_.entries(object)

Parameters: This method accepts single parameter as mentioned above and described below:

• object: This parameter holds the object to query.

Return Value: This method returns the key-value pairs.

Example 1:

// Defining Lodash variable const _ = require('lodash'); // Specifying a function function gfg() {  this.A = 5;  this.B = 10;  this.C = 15; } // Calling the _.entries() function  _.entries(new gfg); 

Output:

[ [ 'A', 5 ], [ 'B', 10 ], [ 'C', 15 ] ]

Example 2: In the below code, a set is taken as the object, hence the function _.entries() returns its entries.

// Defining Lodash variable const _ = require('lodash'); // Initializing a set const object = {a: {b: 1}}; // Calling the _.entries() function  _.entries(object); 

Output:

[ [ 'a', { b: 1 } ] ]

Note: This will not work in normal JavaScript because it requires the lodash library to be installed.
