Absolutely right, That's why.. mene yad krke rakha hai jab bhi array sort Krna ho, (a,b) => a-b for getting accesnding length and (a,b) => b-a for decending length. 😅😅

sort method takes a callback function, which again takes 2 parameters. so sort(function(a,b){}), like this.. now, here a, b means each pair of elements of the array. if a > b, that means they need to be swapped, and we do it by returning a positive value from the callback function. if a < b, that means they are already sorted, no need to swap. we do it by returning a negative number or 0 from the callback function. so the code looks like : sort(function(a,b){ if(a>b) return 1; else return -1 } ) here I have written 1 and -1, but you can return any positive and negative values. now, if a > b, then a-b will always be a positive number, else it will be negative. that's how the following one-liner works perfectly - sort(function(a,b) { return a-b } )

The best js question solution channel really ❤

You call it lexicographic comparison. Or basically, dictionary style comparison.

Bhaiya hm sort function m bina arguments pass kiye use kisi variable m store krke variable ko print kare too..... const arr = [70, 2, 63, 700, 100] const sorted = arr.sort() console.log(sorted)

Sir sorry but char ke ascii value se comparison hota na ki char ka

Sir compaliar kaun sa hai

Didn't know. Thanks 😊

I have a question why the array is changing as const keyword will not allow the value to be changed???

javascript is unpredictable

wired language

❤❤

a-b ka kya logic hai koi bta do

I hate JS
