ReactJS & JavaScript Mock Interview | 🎉 Candidate selected 🎉 | Mid range Engineer 

21:21, the explanation can be more depth if the function expression is defined with var we get a typerror and with both const and let it's a reference error, typerror comes with var as var is global we are able to refer it but since we have a function expression and our var doesn't yet know it, it throws a typerror while with let and const they are not hoisted per say so reference error shows up!

5:05 , line-by-line execution happens in 2 step execution process with the help of the Hoisting concept in JS. So, what basically happens is that though JS interprets line by line it only performs the compilation phase on first priority meaning the variable gets declared, the function gets declared and it ignores all the execution phase like func invocation or variable assignment. Once it's done it performs the execution phase so we can say to understand that the JS engine moves the compilation process on top but it's only for understanding in reality no such moving to top stuff happens.

Asking the exact questions that I got interviewed on my past interviews . Everyone has to know these concepts to get a job . Thank you

Like your javascript snippet part as its most asked question and we often get confused

You have very positive vibes and your energy and that enthusiastic smile is awesome 🧡🧡🧡🧡🧡

I can give ans to first code snippet const a = b = c = 1 can be seen as const a = 1; b = a; c = b; so here b and c are declared without any var let or const so these become global variables and as we know const is a block scope so after function executes and completes a lost its scope and is undefined while b and c are global variable right and we have assigned a number to them so they are showing us type as number. I hope this is clear.

Blown away by the 1st code snippet question!

Snippet 2- As it was an arrow function and as it was called before the declaration it was giving an error.

Sir please make video on frontend end system design like the complex trading app zerodha and money control and how it works

In the first snippet: I think const only applies to 'a' in the declaration and the other two b, c are not block scoped. I may be wrong.

What skill expected for a front end architect position like 12 to 15 years of experience? Please make one video for this for front end. Please help us for scenior persons
