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?
(The Back Quote is intentional) (Sorry for bad explanation)
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'
})
