I’d like to order the same for

id - 15135
id - 50
id - 25

I tried to use

 array.sort

but it didn’t work.

    Can you put the console text here, as text and not image, ? so it makes life easier for those who want to help with an example.

  • sort is a method so it would have to be array.sort() but without seeing how the code is hard to help

var meuArray = [['4togm90gjwegn', 50], ['ef84itjdpodsdf4jg', 25], ['32r8uoijgtsdfsht', 15135]];

//Para ordenar em ordem crescente
meuArray.sort((a, b) => a[1] - b[1]);
//Para ordenar em ordem decrescente
meuArray.sort((a, b) => b[1] - a[1]);

The Sort method, if called without any parameter attempts to sort its array by comparing string values, but when its array is not made up of strings, you can pass a callback function with instructions for the organization.

This function takes 2 arguments, the first and the next item of the array (a and b), so it is up to you to return a number greater than 0 to say that the element a precedes b, or less than 0 to say that b precedes a. Since the values compared are numerical, in which case you can just subtract them.
