How to use Iterative Conversion In Javascript
This method involves iterating through each key-value pair in the Map and constructing a new object that mirrors these pairs. This object is then converted to JSON using JSON.stringify().
Syntax
const mapToJson = (map) => {
const jsonObj = {};
map.forEach((value, key) => {
jsonObj[key] = value;
});
return JSON.stringify(jsonObj);
};
Explanation:
- We create a function mapToJson that takes a Map as an argument.
- We initialize an empty JavaScript object jsonObj.
- We iterate through each key-value pair in the Map using map.forEach(), and for each pair, we assign the key-value to jsonObj.
- Finally, we use JSON.stringify() to convert jsonObj into a JSON string.
Example: Implementation to show how to convert map to JSON in JavaScript.
const mapToJson = (map) => {
const jsonObj = {};
map.forEach((value, key) => {
jsonObj[key] = value;
});
return JSON.stringify(jsonObj);
};
const myMap = new Map([
['name', 'Abdullah'],
['age', 21],
['city', 'New York']
]);
const jsonString = mapToJson(myMap);
console.log(jsonString);
Output
{"name":"Abdullah","age":21,"city":"New York"}
Note: This JSON string can then be parsed back into a JavaScript object using JSON.parse() if needed.
How to Convert Map to JSON in JavaScript ?
In JavaScript, when working with data, you might encounter situations where you need to convert a Map object into a JSON format. This can be useful for sending data over the network, storing data in local storage, or interfacing with APIs that expect JSON data.
Converting a Map to JSON means converting each key-value pair from the Map into a JSON object. JavaScript’s built-in JSON object provides methods to perform this conversion efficiently.
