Understanding Javascript Function Executions — Call Stack, Event Loop , Tasks & more

The calling of this callback function serves as the initial frame in the call stack, and due to JavaScript being single-threaded, further message polling and processing is halted pending the return of all calls on the stack..Subsequent (synchronous) function calls add new call frames to the stack .In the next part, I will show a visual animation of code execution for the above procedure, further explaining what are different types of async functions like tasks, micro-tasks and whose priority in the queue comes first..Also, the hacks like zero delay used to perform some functions.Hope, you like it, feel free to post your valuable comments, to help me improve..
