অনেক ঘোরাঘুরির পরে (প্রায় ৩ বছর টিউটোরিয়াল টু টিউটোরিয়াল) আমি Day 04 পর্যন্ত পৌছেছি। আমার স্বপ্ন জাভাস্ক্রিপ্ট (ফ্রেমওয়ার্ক+লাইব্রেরি) দিয়ে একটা ই-কমার্স সাইট তৈরি করা। আশা করি এবার পারবো। ধন্যবাদ এত সুন্দর টিটোরিয়াল তৈরি করার জন্য।

This video is outstanding, sir! The quality of the content is exceptional, and your explanation is crystal clear. You've truly done an incredible job!

[AgahNnaemeka]

Very very insightful. I had difficulty understanding the switch statement with my training but this is a lot simpler.

[nikshadali]

Loved the clear explanations! This series is a game-changer!

[Alpha-Tube-tw]

Sir. Really You are the true teacher, I'm get a great understanding about javascript, starting from now I can confidentlially code.

[bhaskaranb]

I have purchased a paid JS course but sill I'm taking this course again. There are a lot more things covered in this free course that was not part of the paid course. Thank you so much.

[venkatatvenky]

your sessions are really interesting, its worth to spend one hour for class your way of teaching is really interesting, thanks for giving me right platform to learn JavaScript

[tsamspace]

learning is going on very well making it easy to undersstand

[gurukrish]

Very Superb sir, everything so good ..I took it very seriously so that i will never fear or have unwanted doubts abt my JS skills ...so what I did is that I paid some mini amt to make myself involve into it....😇❤‍🔥

[WWeekes-oxuv]

I understand how to use if else and switch cases and when to use it thank you😀

[dakra]

Instead of an if else tree, I prefer to just use if's and break inside a do { } while (false);:
do {
if (condition1) {statements; break;}
if (condition2) {statements; break;}
if (condition3) {statements; break;}
/* else */ {statements; }
} while (false);

This makes adding, removing, and commenting out lines easier, IMHO. Furthermore, the break can be omitted where appropriate

[SadmanSakibAbir-ri]

Very informative and the way you have explained makes it much easier to understand looking forward to the next lessons

[Stephengicheru-wx]

thank you very much u are the best God bless you

1. JS code runs synchronously and line by line.
2. But using if-else, switch and so on we can skip some part of our code if we want.

if-else if - else :
1. helps us to conditionally run a chunk of code.

switch case:

1. when we need to check deferent scenarios based on one condition than use switch statement. (we can consider it, alternative of if else )
2. it is more performant than if else.
3. but for complex conditions its better to use if-else.
