top 10 JavaScript tricks 

Ali, glad to be back! Thanks for watching!

Ivan, As I said in the video, this particular trick is not to use in the code , its for interview question.

a= a + b; b= a - b; a= a - b; Same code but neat/understandable.

Sumod, so nice of you to share my videos with your friends. :) THanks for watching!

you probably dont care at all but does someone know a trick to get back into an Instagram account?? I somehow forgot the password. I would love any help you can offer me

@Skylar Kendrick instablaster :)

@Stetson Davian i really appreciate your reply. I found the site thru google and im waiting for the hacking stuff atm. Seems to take a while so I will reply here later with my results.

@Stetson Davian It did the trick and I now got access to my account again. I'm so happy:D Thanks so much, you saved my ass !

@Skylar Kendrick You are welcome =)

Yes, I am planning to make some more such videos. I do have another channel which focuses on interviews , its interviewnest do check it out.

Thanks Prasad. :)

There are multiple ways to do it. create three separate projects with their own routing and all . when you do "npm start" , load them on different port . then create a third project with button and links to the URL with different ports.

@@Techsithtube thanks for the response....but no we should have only one port ...for example... localhost:3000/main page Then on click of project2 is should be Localhost:3000/project1 and inside project one if we navigate to projectdetail the path should be project/projectdetail

yes that is a good solution. Thanks for sharing!

Glad you enjoyed it! Thanks for watching!

You can email me . You can join my facebook community for react. Its on my channel page.

@@Techsithtube I already given a join request bro.. Please accept it bro

start with 10 min, do 15 min next day , then 20 min .. day by day increase ..you will be more patient.

Good advice!

can you explain this in detail.

Absoultly value is imutable then plz define me how it modified but if you talk in static type languages like c# java c+, then pass those variable by reference if you dont them it only remain in function scope but if you want to use these swaping values out side the function then you have to pass these variable by refernce

And secondly I appreciate your service and accept that once I saw your video definitly learn new stuff and always seek to learn new things.

I also need this explanation.

let say a = 1, b = 2 , a = a + b ( a=3, b=2) , b = a - b ( a=3, b=1), a = a-b ( a = 2, b=1)

I know how swapping of 2 variables without using 3rd variable works but not able to understand the syntax you used i.e where are we calculating a= a+b in Expression you used

@@sumeetsood232 for instance?

@@sumeetsood232 Hi Sumit, for understanding this concept, You have to know about Operator precedence in JavaScript. In this case, the first precedence is Grouping. I mean 'parentheses'. like this (b+= a -=b). Bear in mind that the Associativity is right to left. So as you can see, we need to calculate the right side of parentheses that it is a-=b and it is equivalent to a=a-b. after calculating, we have a=-1 until know (a=1-2). as well as, we need to calculate the left part of parentheses Ok? It is b+=a. so as I told you before it is equivalent to b=b+a. after calculating, we have b=1 like this (2+(-1)). So far our variables are a =-1, b=1. In the next step, we need to calculate the rest of the logic of the code which is a=(b)-a. so as you know we have b Ok? we only need to put it so a =2. like this a=1-(-1). that's it :-). a=2 and b=1. I hope that makes sense to you.

Ramin, I agree with annoying adds. Let me tell you little bit of history about what is happening so you would understand. RU-vid has reduced income by 50% last year. As a content creator, I spend significant amount of time in producing these videos. 10 min video takes me about 7hrs to produce from concept to final upload. If I want to continue making these video for free, I had to look for some other income source. Hopefully that answer your question.

@@Techsithtube Alright, alright, so maybe it's time to move on! Maybe this way of doing business is dead. Making video and publishing them on youtube is not working! Begginers don't learn like this. They need an interactive environment and community to learn for real. RU-vid was a cash grab for too many years. Most of programming channels are misleading and worthless. Students need to know how they could put their knowledge into practice. These videos lead them to nothing. It's time to do something really different for teaching people if you really care.
