0 0 1 minute read

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();
