JavaScript sort 2D array

Question

So I have an array in JS which looks something like this:

let arr = [["p1",5],["p2",7],["p3",2]]

How would I sort it in descending order by the second value? So that it would look like this:

[["p3",2],["p1",5],["p2",7]]

Thanks!

Answer 1

let sorted = arr.sort((a,b) => a[1] - b[1]);

Answer 2

By the way, your specifications is ascending order instead of descending order.
