Learn the Date Object by Building a Date Formatter - Step 21

[Zaza08]

Tell us what’s happening:

one question. whats the point of doing split reverse and join in this code snippet ? Cant we just put formattedDate value as ${year}-${month}-${day} instead and then we dont have to split and reverse it? Are they just teaching us to do split and reverse and join or is it necessary? just confused about it

Your code so far

const currentDateParagraph = document.getElementById("current-date");

const dateOptionsSelectElement = document.getElementById("date-options");

const date = new Date();

const day = date.getDate();

const month = date.getMonth() + 1;

const year = date.getFullYear();

const hours = date.getHours();

const minutes = date.getMinutes();

const formattedDate = `${day}-${month}-${year}`;

currentDateParagraph.textContent = formattedDate;

dateOptionsSelectElement.addEventListener("change", () => {

 switch (dateOptionsSelectElement.value) {
    case "yyyy-mm-dd":
      currentDateParagraph.textContent = formattedDate
        .split("-")
        .reverse()
        .join("-");

  }

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

@Zaza08

Are they just teaching us to do split and reverse and join

yes. this is the reason.
Especially since the following project , which is the first certification project, uses it

hope that helps
