function firstFunction() { // do something return “testing 123″; } var test = firstFunction(); // this will grab you the return value from firstFunction(); alert(test); Here is what the above code is Doing: 1. We define a function called firstFunction() 2. We return a string “testing 123” 3. We assign the return value of firstFunction()…
// sketch.js function setup() { var canvas = createCanvas(100, 100); // Move the canvas so it’s inside our . canvas.parent(‘sketch-holder’); background(255, 0, 200); } Here is what the above code is Doing: 1. We create a canvas that’s 100×100 pixels. 2. We move the canvas so it’s inside our div with the id of sketch-holder….
function rotLeft(a, d) { let rslt = a.slice(d).concat(a.slice(0,d)); return rslt } Here is what the above code is Doing: 1. slice(d) – returns a new array with the first d elements removed 2. slice(0,d) – returns a new array with the last d elements removed 3. concat() – combines the two arrays into one
function App() { const download = e => { console.log(e.target.href); fetch(e.target.href, { method: “GET”, headers: {} }) .then(response => { response.arrayBuffer().then(function(buffer) { const url = window.URL.createObjectURL(new Blob([buffer])); const link = document.createElement(“a”); link.href = url; link.setAttribute(“download”, “image.png”); //or any other extension document.body.appendChild(link); link.click(); }); }) .catch(err => { console.log(err); }); }; return ( download(e)} > download…
let difference = arr1.filter(x => !arr2.includes(x)); Here is what the above code is Doing: 1. We create a new array called difference. 2. We use the filter() method to loop through each element in the arr1 array. 3. We use the includes() method to check if the current element is in the arr2 array. 4….
