So, Advanced JS?

Javascript is a single threaded single concurrent language

• This means that JS can handle only one task at a time (or one piece of code)
• It has a single call stack

Call stack

• It is a data structure which records the function calls
• In Assembly we have the stack too! :) (basically in any program)
• If we call a function, we push this function to the call stack. If we return some function, we pop this function from the call stack.
• Stack overflow error is when we ran out of memory in the stack or we had reached the max of the call stack.
• Everything in Javascript pass throught the call stack.
• Some things whill block it and execute immediatly and some things will be handled later

Event Loop

• Observes the call stack. IF it is empty, it will look to microTasks and Tasks

Heap

• Memory allocation, variables and objects

V8

• Is the engine that interprets our JS code

Libuv

• Is a C++ Scheduler, used to Event Lopp or Call Stack

NodeJS

• Is a C++ Program that is in the middle of our JS Code, our V8 Interpreter and our Libuv Scheduler
