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:

Javascript




// 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.

 

Javascript




// 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.
