Managing user authentication and authorization is a very difficult task, and a failure can cost much more than unauthorized access to your application.

After authentication, a user or process generally also goes through an authorization process to determine whether the authenticated entity must be authorized to access a protected resource or a protected system. A user can be authenticated, but will not have access to a resource if that user is not authorized to access it.

To understand both concepts let’s make it simple for you.

The synchronous function let’s asume that you are in video game , each level requires certain score to move for the next .In this case we are moving level by level , this is how the synchronous function works.

For the asychronous function, let’s asume that each level devided into mini-levels and in order to finish the level you are asked to score all the mini-levels.

So the Asynchronous function is that if you’re doing multiple things at the same time, you don’t have to wait until the end of the current one before moving on to the next one. Unlike the synchronous function where only one operation can be in progress at a time.

we use recursion in situations when we can repeat the function that created into the same function but the condition change
like example : if you will counting from 1 to 7 with your fingers every time when you will count the fingers you will close until you come to 7
this is the condition in recursion can be n =n-1 and in other situation can be n=n+1 and it change with any situation
