Lodash _.toPairs() Method

Lodash _.toPairs() method is used to create an array of enumerable string key-value pairs for an object that can be consumed by the _.fromPairs() function. If the object is a map or set, its entries are returned.

Syntax:

_.toPairs(object);

Parameter:

• object: This parameter holds the object to query.

Return Value:

This method returns the array of key-value pairs.

Example 1: In this example, we are getting a pair of the given function by creating a prototype of it by the use of the lodash _.fill() method.

Javascript

// Requiring the lodash library
const _ = require("lodash");

function Fb() {
    this.id = 2045;
    this.username = 'fb_myself';
    this.password = 'fb1234';
}

// This will not be included in the array
Fb.prototype.email = 'myself@gmail.com';

// Use of _.toPairs() method
console.log(_.toPairs(new Fb));

Output:

[["id", 2045], ["username", "fb_myself"], ["password", "fb1234"]]

Example 2: In this example, we are getting a pair of the given object by the use of the lodash _.fill() method.

Javascript

// Requiring the lodash library
const _ = require("lodash");

let GfG = {
    'x': 1,
    'y': 2
}

// Use of _.toPairs() method
console.log(_.toPairs(GfG));

Output:

[['x', 1], ['y', 2]]
