The clear() method of p5.TypedDict in p5.js is used to remove all the key-value pairs in the typed dictionary. A key-value pair is a set of two values that are mapped to each other. These values can be accessed by querying this dictionary using the key portion of the pair. A typed dictionary can store multiple key-value pairs that can be accessed using the methods of the dictionary.
Syntax:Â

Parameters:Â This method does not accept any parameters.
