So, let's say I have an array of months. I want it to say what the item position is and the item name, and create a sort or list instead of having it be "january,febuary,march,april". Example below
``ITEM_POSITION`` - MONTH_NAME ``0`` - January ``1`` - Feburary ``2`` - March ``3`` - April and so on... How would I list the months like this?

Are you familiar with for loops? How about something like the following:
const months = ["january", "february", "march", "april"]; // print your header here // ... for (let idx = 0; idx < months.length; idx++) { // print desired info for each month here // this isn't the exact format you want, but here's a hint console.log(idx + " - " + months[idx]); } // print any "footer" here // ... This is not the only way to achieve what you want, but is probably the most straightforward.
let monthMsg = '' at the top, then monthMsg += <format you want> inside the loop instead of console.logmonthMsg += idx + " - " + months[idx], and it would just give me 0 - january1 - february2 - march3 - april Any ideas?You can store months in an array. Each element has its own index according to its position. Another way is to create an object and asign key/value pairs.
//ARRAY let arr = ['January', 'February', 'March', 'April']; //Access each arr element arr[0]; // 'January' arr[1]; // 'February' //Iterate arr elements arr.map(x => console.log(x)); // map method (iterates each element) and logs in console //Sort console.log(arr.sort()); // sort alphabetically //OBJECT let obj = {0: 'January', 1: 'February', 2: 'March', 3: 'April' }; console.log(obj); //Access obj properties obj[0]; // 'January'; obj[1]; // 'February'I assume you're trying to create an object like structure.
like:
{ item_position: 0, month: 'January' } you can do it like this (Even though is really redundant):
const months = ['january', 'february', 'march']; const months_list = []; months.forEach((month, index) => { months_list.push( { "ITEM_POSITION" : index, "MONTH_NAME" : month } ) }) months_list.forEach(item => { console.log(item.ITEM_POSITION, item.MONTH_NAME) // 0, 'january' })
