The program below illustrate the createNumberDict() function in p5.js:
Example 1:
function setup() { createCanvas(500, 200); textSize(20); // Creating a number dictionary // with the given key and value pair let mydict = createNumberDict("19", "1999"); // Accessing the data using the data property text('The dictionary has the following data under "19":', 20, 20); text(mydict.data["19"], 20, 40); // Checking if a key exists in the dictionary text('The dictionary has the "25" key present:', 20, 80); text(mydict.hasKey("19"), 20, 100); text('The dictionary has the "100" key present:', 20, 140); text(mydict.hasKey("100"), 20, 160); } |
Output:
Example 2:
function setup() { createCanvas(600, 200); textSize(20); let squaresObject = { 2: 4, 3: 9, 4: 16, 5: 25 } // Creating a number dictionary // with the above object let mydict = createNumberDict(squaresObject); // Accessing the data using the data property text('The dictionary has the following data under key "2":', 20, 20); text(mydict.data["2"], 20, 40); text('The dictionary has the following data under key "4":', 20, 80); text(mydict.data["4"], 20, 100); text('The dictionary has the following data under key "5":', 20, 140); text(mydict.data["5"], 20, 160); } |
