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:Â
set( key, value )
Parameters:Â 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); } |
