node app.js
Output:
String representation of object : A=Book&B=Pen&A=Pencil
Example 2:
Filename app.js
javascript
// Node.js program to demonstrate the // URLSearchParams.toString() method // Importing the module 'url'const http = require('url');// Creating and initializing // URLSearchParams objectconst params = new URLSearchParams();// Appending value in the objectparams.append('Beginner', 'code');params.append('for', 'eat');params.append('Beginner', 'sleep');// Getting string representation// by using toString() apiconst value = params.toString();// Display the resultconsole.log("String representation" + " of object : " + value); |
