bryancodesjs / useReduce.js
Created March 8, 2023 03:49
A brief example of how Array.prototype.reduce() can be used
const transactions = [
{ id: 1, amount: 100 },
{ id: 2, amount: 200 },
{ id: 3, amount: 300 },
{ id: 4, amount: 450 }
]
const useReduce = transactions.reduce((acc, curr) => {
return acc + curr.amount;
},0);

bryancodesjs / returnDescendingOrder.js
Created January 30, 2022 04:05
take any non-negative integer as an argument and return it with its digits in descending order. Essentially, rearrange the digits to create the highest possible number.
//this is an example integer
const myInt = 52132;
function descendingOrder(n) {
if (n > -1) {
let toArr = Array.from(String(n), Number);
let sorted = toArr.sort((a, b) => a - b).reverse();
let joined = sorted.join("");
return parseInt(joined);
}

Created January 22, 2022 03:26
Fetch data from an API and appending the results to an unordered list
//this is a mock API I made for the occasion
const submitUrl = 'https://retoolapi.dev/QqocMc/data';
//this selects the unordered list with the id 'list' on the html template
//you should have that set up beforehand
const htmlListNode = document.getElementById('list');
//Use the fetch method and pass it the url of the API
fetch(submitUrl)
.then(res => res.json()) //parse the response and then...
.then(data => {
let length = data.length; //save the length of the array to use it as a reference in the loop

retrieve data from an API using XMLHttpRequest and then iterate over the results
//API url
const quotesUrl = 'https://quote-garden.herokuapp.com/api/v3/quotes'

Count from 1 to 100 and print a message every time a multiple of 3 or 5 is found.
function findMultiples() {
let baseNumer = 0;
for(let i = 0; i<100 ; i++) {
baseNumer ++;
console.log(baseNumer);
if(baseNumer % 3 == 0) {
console.log('multiple of 3 found');
} else {
if (baseNumer % 5 == 0) {
console.log('multiple of 5 found');
