How can i make a click button when do i click make sort(a-b) array and then click again to sort(b-a)

Here is my question
How can i make a click button when do i click make array.sort(x-y) and then click again to make array.sort(y-x)

i’m already have the function but i’m confuse how to do it…

let me clarify my question: when do i click on button i make sort to array from bigger to smaller number and then i would like to press on the same button to make the array sort from smaller to bigger

here is my code:

$(".lower").click(() => {
    colorsValueMenu("highest", "spot", "gainers", "losers", "lower")
    highest = arrayCoinsD.sort(function (a, b) { return b.quote.USD.percent_change_24h - a.quote.USD.percent_change_24h })
    createCoinDiv(arrayCoinsD, arrayCoinsI)
    $(".lower").click(() => {
        colorsValueMenu("lower", "spot", "gainers", "losers", "highest")
        lower = arrayCoinsD.sort(function (a, b) { return a.quote.USD.percent_change_24h - b.quote.USD.percent_change_24h })
        createCoinDiv(arrayCoinsD, arrayCoinsI)
    })
})

it’s work but just on the first & second time… i want to make it like toggleClass action for every single click

>Solution :

You should make your code DRY (Don't Repeat Yourself)

You can create a flag and change the operations as per the flag as:

let flag = "high";

$(".lower").click(() => {
  //   Highest
  colorsValueMenu(
    flag === "high" ? "highest" : "lower",
    "spot",
    "gainers",
    "losers",
    "lower"
  );
  highest = arrayCoinsD.sort(function (a, b) {
    return flag === "high"
      ? b.quote.USD.percent_change_24h - a.quote.USD.percent_change_24h
      : a.quote.USD.percent_change_24h - b.quote.USD.percent_change_24h;
  });

  createCoinDiv(arrayCoinsD, arrayCoinsI);
  flag = flag === "high" ? "low" : "high";
});
