How does querystring.parse work?

The querystring.parse function is a part of the Node.js core library and is used to parse a query string and return an object of key-value pairs. To accomplish this, the function accepts two arguments: str and sep. The str argument is the query string to be parsed. The sep argument is an optional separator character that can be used to split the key-value pairs in the query string. The default separator is &. The function parses the query string into an object by splitting it into key-value pairs using the separator character, decoding each key and value using URL decoding, and storing each pair in an object as a property-value pair. If a key appears more than once in the query string, its value will be an array of all the corresponding values. If the query string is empty, the function returns an empty object. By using the querystring.parse function, developers can easily parse query strings and extract the key-value pairs they contain, which can be useful in scenarios such as web development, where query strings are often used to pass data between client and server.

const querystring = require("querystring");

const query = "name=John&age=30&hobbies=coding&hobbies=gaming";
const parsedQuery = querystring.parse(query);

console.log(parsedQuery);

In this example, we're using the querystring.parse function to parse a query string and convert it into an object. We define a query variable that contains a simple query string with multiple key-value pairs. We use the querystring.parse function to parse the query string into an object and store it in a parsedQuery variable. We log the parsedQuery object to the console, which will output the following: css Copy code
