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:
clear()
Parameters: This method does not accept any parameters.
The example below illustrates the clear() method in p5.js:
Example:
Javascript
function setup() { createCanvas(550, 500); textSize(16); let tmpObj = { "Statue of Unity" : "182 m" , "Spring Temple Buddha" : "128 m" , "Ushiku Daibutsu" : "100 m" , "Great Buddha of Thailand" : "92m" }; // Create a new dictionary let stringDict = createStringDict(tmpObj); text( "New string dictionary created " + "with four keys" , 20, 40); // Check for a key let existOne = stringDict.hasKey( 'Spring Temple Buddha' ); text( "Dictionary has key " + "'Spring Temple Buddha': " + existOne, 20, 80); // Check the current size let currSize = stringDict.size(); text( "Current size of the dictionary: " + currSize, 20, 100); // Clear the dictionary stringDict.clear(); text( "Dictionary has been cleared!" , 20, 140); // Check for a key again existOne = stringDict.hasKey( 'Spring Temple Buddha' ); text( "Dictionary has key " + "'Spring Temple Buddha': " + existOne, 20, 180); // Check the current size again currSize = stringDict.size(); text( "Current size of the dictionary: " + currSize, 20, 200); } |
