Convert Object to Map in JavaScript

Introduction

In this lab, we will explore how to convert an object to a Map in JavaScript. We will use the Object.entries() method to convert the object to an array of key-value pairs, and then use the Map constructor to convert the array to a Map. This technique can be useful when working with data that requires the use of a Map data structure.

Here's how to Convert Object to Map

To convert an object to a Map, follow these steps:

Open the Terminal/SSH and type node to start practicing coding.

Use Object.entries() to convert the object to an array of key-value pairs.

Use the Map constructor to convert the array to a Map.

Here's an example code snippet:

const objectToMap = (obj) => new Map(Object.entries(obj));

You can use the objectToMap() function to convert an object to a Map. For example:

objectToMap({ a: 1, b: 2 }); // Map {'a' => 1, 'b' => 2}
