In javascript for comparing the equality we can use both == and === depends on our specific development criteria. So it's better to know the difference between them.
please check the gif image attached

Array :

let k=[1,3,11,2,33,22]

k.sort()

Result :
[1,11,2,22,3,33]

Here the array just sorted based on the ASCI values, so how to make it such way that it can return the array in ascending sort order.

k.sort((a,b)=>{return a-b})
use the fat arrow function
Result : [1,2,3,11,22,33]

descending sort order.
k.sort((a,b)=>{return b-a})

Result : [33,22,11,3,2,1]
