// 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);

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

[@dumptruck3354]

lol

[@JadeWays]

Thank You! you make it easy to understand.

[@mr.joecool]

very cool, thanks for sharing!

[@latostadaa]

Thank you, you made this easy to understand

[@oshione7873]

This guy is such a clutch

[@monayzah]

Thank you!

[@jamshedmorio1045]

Thanks brother this video is very easy to understand

[@theMadZakuPilot]

great vid bro.

[@malablondi77]

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

[@vallunacoder.wecodetogether]

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

[@kathikr9360]

thank you

[@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.

[@kathikr9360]

thanks again

[@tanviranjum695]

What’s the complexity of this sort() method

[@Drelka]

thanks bro

[@hunin27]

are these old videos or are they new?

[@BroCodez]

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

[@hunin27]

ok ok. thanks!@@BroCodez

[@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

[@LearnwithRandomYoutuber]

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

[@ArconicTower]

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

[@user-mk2md9pu5m]

Cool

[@user-mk2md9pu5m]

Thanks for like

[@allhailalona]

i would think squidward is more intelligent than spongebob

[@khansikki]

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}}
