Query String Converter
This lesson is part of Web Developer Tools · All levels
Summary
Query String Converter changes the URL after the question mark to a key-value pair, or vice versa. Query strings use the symbol & as a separator of parameters and = between key and value. The special characters in the value must be encoded so that they are not considered part of the structure. In the browser, URLSearchParams provides a practical way to read and form query strings.

- Sign & separate the parameter and = separate the key by the value
- The value needs to be encoded so that the particular character does not damage the structure
