[@VishalGupta-bf9be]

So awesom and informative session and I request you for deliver more content regarding this. Also I have one doubt that console is Web api so will it be go for the queue 🤔🤔 and will go for the stack or directly it will be executed 🤔🤔 please clear doubt if it is possible. 😑

[@CodersGyan]

Console.log is a synchronous task. So it will go on stack and executed. things like setTimeout, intervals, promises goes in the queue that’s why we call it because they don’t block the stack. That’s why we call them asynchronous tasks. 😊

please explain this key word

[@shubhamgupta-bl1tr]

Still having doubt ..why clouser is working in case of let not of var ... Actually clouser part is not clear

[@CodersGyan]

Well, Let me try to explain little bit differently. When we are using var keyword, here var is behaving like a global variable. That's why callback which is inside timeout is not capturing that variables value until loop ends. But incase of let keyword, which is block scope, which is only available inside of THAT block, so the callback has to close value of i inside the closure. That's why, it keeps appropriate value for every iteration. Following paragraph might help you to understand: We need to keep in mind when a JavaScript function is defined inside a loop with variables, it establishes something known as closures. So what closures in JS ensure is this: make the local lexical environment available to the inner function. A lexical environment comprises references to the variables within a loop or a function and is used when the same is invoked. Hence, when we initialize using let inside the loop, the inner function (which is an async callback function) knows that the next time there is a callback, the variable logged must be local and I need to update instantly or perform the “closure” of the variable instantly. Whereas, when var is used, it’s scope is not block. This doesn’t trigger the async function for a change in the value and the variable is only “closed” after the loop has completed and hence the value 5, in our case. I hope, this will clear your doubt. Feel free to ask more questions 😊

Kya aap satisfied hai is answer se😂😂

isbnt it due to arrow function?
