JSON/GET request string conversion

1. JSON is a lightweight data interchange format based on a subset of the JavaScript programming language, but it is independent of any specific language or platform.

2. JSON uses text to store and represent data, making it easy to read and write, as well as easy for machines to parse and generate.

3. A GET request string is part of a URL used to pass data to the server.

4. A GET request string begins with a question mark (?), followed by key-value pairs separated by ampersands (&).
