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); } |
