URL Encoder/Decoder

// For query parameter values (encodes everything)
const query = encodeURIComponent('Hello World!?');
// Result: "Hello%20World!%3F"

// For full URLs (preserves :, /, ?, #, etc.)
const url = encodeURI('https://example.com/search?q=hello world');

// Decode
const decoded = decodeURIComponent('Hello%20World');
// Result: "Hello World"

from urllib.parse import quote, unquote, urlencode

# Encode a string
encoded = quote('Hello World!?')
# Result: "Hello%20World%21%3F"

# Encode query parameters
params = urlencode({'q': 'hello world', 'page': 1})
# Result: "q=hello+world&page=1"

# Decode
decoded = unquote('Hello%20World')
# Result: "Hello World"

// For query strings (space = +)
$encoded = urlencode('Hello World!?');
// Result: "Hello+World%21%3F"

// RFC 3986 compliant (space = %20)
$raw = rawurlencode('Hello World!?');
// Result: "Hello%20World%21%3F"

// Decode
$decoded = urldecode('Hello%20World');
// Result: "Hello World"

import "net/url"

// Encode query parameter
encoded := url.QueryEscape("Hello World!?")
// Result: "Hello+World%21%3F"

// Encode path segment
pathEncoded := url.PathEscape("Hello World")
// Result: "Hello%20World"

// Decode
decoded, _ := url.QueryUnescape("Hello%20World")
// Result: "Hello World"
