This is not just a interview question video , but the whole documentation of JavaScript in compressed form ,and really far better than those coding tutorials of 10 to 15 hours. Animations, presentation and using code examples and no garbage talking, point to point things make it seems like a paid course. You can jump to Node js or React after watching this easily Thanks a lot Sir

woww... tears in my eyes. They always said, make videos like other teachers where you type the code. I always said, my goal is to explain the concepts clearly & within time. My code typing will not make viewers good coders. Code yourself to become good coders.

In JavaScript, when you declare a variable and assign it a primitive value, such as var a = 30;, the memory is allocated to store the value 30 in a specific location. Later, if you write a = 45;, it doesn't mean that a new memory location is allocated. Instead, the value at the existing memory location is updated to 45. But sir, you said different memory is allocated.sir,could you please verify your answer.

New location means, new memory address. That is immutability. Explore more.

i have a littele confsuion on differnce between primitive and non primitive data type question in that u said ,we assign a new value to the varible it stored in new location as of my knowldge In JavaScript, primitive data types (such as numbers, strings, and booleans) are indeed immutable. When you assign a new value to a variable holding a primitive type, the new value is stored in the same memory location. kindly expalin this sir which one is correct

Hi Admin, Your content is good do mind adding async await promise promise.race,promise.all concepts as well. Protoype inheritance cors errors. What happens when you add async or defer keyword to the script tag and there order of exection. Event loop concepts since JavaScript is single thread how does it handle concurrent request. If condition and loops I don't think interviewers will be interested in asking question as it is present in all the programming language.debouncing/throttling and function curry and how to write polyfill for bind method concept also has been skipped. Please come up with all the concept

Hi, Thank you for this awesome content, really very useful for interview, appreciate your efforts in putting this up. I have a question which was asked in one of the interview. Question: Guess the output? ********************************************* console.log('start') const fn = () => (new Promise((resolve, reject) => { console.log(1); resolve('success') })) console.log('middle') fn().then(res => { console.log(res) }) console.log('end') *********************************************** OUTPUT is as mentioned below *********************************************** start middle 1 end success *********************************************** Can you please explain the flow behind this. Thanks in advance Regards, Anil Sebastin
