Query String
This is a suite of JavaScript utilities for the bidirectional conversion and manipulation of URL components and query parameters. It provides a mechanism for parsing URL query strings into data objects and serializing those objects back into URL-encoded strings.
The library includes functions for filtering, isolating, and modifying parameters within a full URL or query string. It supports the construction of complete web links by combining base addresses with formatted query parameters.
The toolset covers data transformation primitives such as alphabetical key sorting, input sanitization, and type-casting for numbers and booleans. It also handles the stringification of nested arrays and the removal of specific keys via predicate-based filtering.
