The Standard URL and URLSearchParams APIs
Introduced across all modern browsers, the native URL constructor automatically parses protocol, hostname, port, pathname, search, and hash fragments.
The searchParams property provides convenient utility methods: get() retrieves a parameter, getAll() retrieves arrays of duplicate keys, set() updates values, and append() adds new parameters.
Handling Multi-Value Parameters and Encodings
Query strings often contain special characters like spaces, ampersands (&), and plus signs (+).
URLSearchParams automatically applies application/x-www-form-urlencoded percent-encoding, preventing common bugs where unencoded ampersands split single parameters into multiple broken keys.

Frequently Asked Questions
What is the difference between encodeURI() and encodeURIComponent()?
encodeURI() is intended for complete URLs and preserves delimiters like :, /, ?, and &. encodeURIComponent() encodes every special character, making it mandatory for encoding query parameter values.
Can I strip tracking UTM tags automatically with DocSwift?
Yes! The URL Parser & Analyzer allows 1-click removal of utm_source, utm_medium, utm_campaign, and fbclid tracking tags.
