Not pointing out mistakes but you wrote for isAfter : before record gets saved, I was making notes but thought this is not correct so i saw you also have the same thing but you explained it right. but as i was making notes from your ppt i thought it to be wrong please take caution with the PPT.
Apart from that amazing job I'm going to finish the entire playlist thank you for this playlist.

[@sagarikabhelkar3477]

Please see to it I think after triggers it will be fired after the record is saved you said it correctly but there's a printing mistake for isAfter context variable

[@sfdcninjas]

Great observation!!
Thanks for noticing there is a printing mistake.

Hey buddy its late but did you got the answer

[@hemantsinghbisht4371]

Hi can anyone tell me why I'm not getting any changes in account object even tho I have done all the steps just like video .! 😮

[@sfdcninjas]

Hi can you please share your code

[@amitbagade3277]

Sir How to write Test Class For this ?

[@sfdcninjas]

you just need to create test data in your test class according to trigger, don’t worry I will upload test classes for all triggers soon.

[@oindrisen1932]

@@sfdcninjas have you uploaded the test classes yet?

[@sfdcninjas]

Hi , don’t worry i am going to start a video series on test classes soon

[@memesv3.093]

Hi Sir, Thanks for the explanation
I wrote the code below for the scenario mentioned in this video (This code also works).
Can you please let me know the drawbacks of this code as compared to yours
trigger AccountTrigger on Account (after update) {

Set accIds = new Set();
if(Trigger.isAfter && Trigger.isUpdate){
for(Account a: Trigger.new){
accIds.add(a.Id);
}

List conList = [SELECT Id, Phone from Contact where AccountId IN: accIds];

for(Account acc: Trigger.new){
for(Contact con: conList){
con.Phone = acc.Phone;
}
}

update conList;
}
}

[@sfdcninjas]

Hi Buddy, 1. if your code is dependent on change of particular field then before record id in set you can apply a check on it like if(ac.Phone != null && a.phone != trigger.oldMap.get(a.Id).Phone)
{
accIds.add(a.Id);
}
2. null checks on the list which is being used in code to avoid null pointer exception.
3. bulk updation
