The set() method of p5.TypedDict in p5.js is used to add or modify the value at the given key of the 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:
set( key, value )
Parameters: This method accepts two parameters as shown above and discussed below:
- key: This is a number or string that denotes the key that has to be added to the dictionary.
- value: This is a number or string that denotes the value that has to be added to the dictionary.
The example below illustrates the set() method in p5.js:
Example:
Javascript
function setup() { createCanvas(550, 300); textSize(16); // Create an empty dictionary let stringDict = createStringDict({}); text("New empty string dictionary created", 20, 20); // Get the value at the given key let valOne = stringDict.get('Apple'); text("The value at key 'Apple': " + valOne, 20, 60); // Add the given key to the dictionary // specifying the key and value stringDict.set('Apple', '$340 billion'); text("New key 'Apple' added with " + "set() method", 20, 100) // Get the value at the given key valOne = stringDict.get('Apple'); text("The value at key 'Apple': " + valOne, 20, 140); // Change the value of an already set key stringDict.set('Apple', '$352 billion'); text("Value at key 'Apple' modified using " + "the set() method", 20, 180) // Get the value at the given key valOne = stringDict.get('Apple'); text("The value at key 'Apple': " + valOne, 20, 220); } |
