What are querystring-es3's main functionalities?

Parsing query strings

This feature allows you to parse a query string into an object, where each key-value pair in the query string becomes a key-value pair in the object.

var querystring = require('querystring-es3');
var parsed = querystring.parse('foo=bar&abc=xyz&abc=123');

Stringifying objects

This feature allows you to serialize an object into a query string, with support for nested objects and arrays.

var querystring = require('querystring-es3');
var stringified = querystring.stringify({ foo: 'bar', baz: ['qux', 'quux'], corge: '' });

Escaping and unescaping

This feature provides methods for percent-encoding and decoding strings, which is useful for sanitizing input and output for URL query strings.

var querystring = require('querystring-es3');
var escaped = querystring.escape('[e-mail]');
var unescaped = querystring.unescape('foo%40bar.com');
