The remove() method of p5.TypedDict in p5.js is used to remove the given key-value pair from 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:
remove( key )
Parameters: This method accepts a single parameter as shown above and discussed below:
- key: This is a string that denotes the key that has to be checked in the dictionary.
The example below illustrates the remove() method in p5.js:
Example:
Javascript
function setup() { createCanvas(550, 400); 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 string dictionary let stringDict = createStringDict(tmpObj); text("New string dictionary created", 20, 20); // Checking the size of the dictionary let currSize = stringDict.size(); text("The current size of the " + "dictionary is: " + currSize, 20, 40); let existOne = stringDict.hasKey("Statue of Unity"); text("Dictionary has key " + "'Statue of Unity': " + existOne, 20, 80); let existTwo = stringDict.hasKey("Spring Temple Buddha"); text("Dictionary has key " + "'Spring Temple Buddha': " + existTwo, 20, 100); // Removing one key stringDict.remove("Spring Temple Buddha"); text("One key removed from the dictionary", 20, 140); // Checking the size of the dictionary again currSize = stringDict.size(); text("The current size of the dictionary is: " + currSize, 20, 160); // Checking for the removed key existTwo = stringDict.hasKey("Spring Temple Buddha"); text("Dictionary has key " + "'Spring Temple Buddha': " + existTwo, 20, 200); // Checking the other keys let existThree = stringDict.hasKey("Ushiku Daibutsu"); text("Dictionary has key " + "'Ushiku Daibutsu': " + existThree, 20, 220); } |
