// sort() = method used to sort elements of an array in place.
// Sorts elements as strings in lexicographic order, not alphabetical
// lexicographic = (alphabet + numbers + symbols) as strings
// ---------- EXAMPLE 1 ----------
const numbers = [1, 10, 2, 9, 3, 8, 4, 7, 5, 6];
numbers.sort((a, b) => a - b); //FORWARD
numbers.sort((a, b) => b - a); //REVERSE
console.log(numbers);
// ---------- EXAMPLE 2 ----------
const people = [{name: "Spongebob", age: 30, gpa: 3.0},
{name: "Patrick", age: 37, gpa: 1.5},
{name: "Squidward", age: 51, gpa: 2.5},
{name: "Sandy", age: 27, gpa: 4.0}]
people.sort((a, b) => a.age - b.age); //FORWARD
people.sort((a, b) => b.age - a.age); //REVERSE
people.sort((a, b) => a.gpa - b.gpa); //FORWARD
people.sort((a, b) => b.gpa - a.gpa); //REVERSE
people.sort((a, b) => a.name.localeCompare(b.name)); //FORWARD
people.sort((a, b) => b.name.localeCompare(a.name)); //REVERSE
console.log(people);

Exactly how a tutorial should be (in my opinion). Short, on point (no unnecessary talking), with relatable (easy to understand) examples. I give this video 10/10. Thank you for making it.

[@Flash11111]

agreeed

[@alexkiiru1283]

Thank you dude.
Lol You did squidward dirty giving him a gpa lower than spongebob

bro, yer a dang champion!

[@syuzannastepanyan374]

Great job! Admire your JS and language abilities

[@omar5695]

Thank you! I was getting the difference between lexicographic and alphabetical

[@JardaniJavanavič]

very cool, thanks for sharing!

[@JamieDawsonCodes]

1:40 - Thanks for explaining the a - b thing in sort(). I didn't understand what was going on under the hood.

[@raniv5132]

Still,I could nt understand this thing ..could yu explain with example?

[@JamieDawsonCodes]

@@raniv5132 Sure thing! Here's what's happening:
If the return value is negative, a should come before b (i.e., a is less than b).
If the return value is positive, a should come after b (i.e., a is greater than b).
If the return value is zero, the order of a and b remains unchanged with respect to each other.

[@meowmeowkami]

​@@raniv5132 basically you swap (a, b) if the calculation after that is positive.
Normal Sorting
(1, 10) => 1 - 10 --- negative = no swap (normal sorting)
(2, 1) => 2 - 1 --- positive ( (2,1) becomes (1,2) )
Reverse Sorting
(1, 10) => 10 - 1 --- positive = swap
you manipulated the function from (1 - 10) to = (10 - 1), which gets a positive result, which results in swapping, which result in reverse sorting.
(1, 10) => 10 - 1 ---- positive = (1, 10) becomes (10, 1)

They're new but unlisted since I still need to create thumbnails

Thanks brother this video is very easy to understand

Thank You! you make it easy to understand.

[@malablondi77]

this helped in understanding how sort() works but i need to sort the outputs of mathemetical functions , how do you do that?

[@peterarcuri3291]

As always, thank you bro code!!

[@LearnwithRandomYoutuber]

Why sort method works for only numbers below 10 ? Like wise in example apart from using Arrow function

[@user006_SKVN8G6LH]

if you sorted words "az" and "b", az is first because "a" is before "b"
if you sorted numbers "10" and "2", 10 is first because the "1" in 10 is before "2"

[@rgraptor2542]

I'm pretty sure it works for numbers greater than ten? ((a, b) => a - b) In another video a guy explains that it subtracts b from a (in this case) and if the answer is greater than 0, b comes first. If the answer is less than 0, a comes first.
so ((a, b) 1324 - 549) the answer is 775 which is greater than 0 so b comes first
((a, b) 342 - 1293) the answer is -951 which is less than so a comes first

Hey Bro!
Thank you!
Can I keep the original order?
And sort into another array?

[@theMadZakuPilot]

great vid bro.

[@tanviranjum695]

What’s the complexity of this sort() method

[@dennistaranchuk4198]

Life saver

[@shieldanime6968]

so the parameter a is the the first and the parameter b is the second..
can we switch the two parameter so that b is the first and a is the second? just like this? in the number.sort((b,a) => b - a)

[@BrahimBrahim-vs5np]

yep it the same as number.sort((b,a) => b - a) it is just a naming

hey Bro thanks for your videos, can you make some projects to understand how to use all this JavaScript methods for a website ?

i want re-sort object according to name preserving keys
//js
const people = {1:{name:'carole',age:13},2:{name:'bob',age:12},3:{name:'alice',age:11}}
//required output
people = {3:{name:'alice',age:11},2:{name:'bob',age:12},1:{name:'carole',age:13}}
