Asynchronous Programs:

What is asynchronous Programming?

• Asynchronous programming is a method of parallel computer programming that enables a process to run separately from the primary function of the program.
• Once the process completes, it communicates this information and may impact the primary function.
• Asynchronous programming often helps reduce or prevent wait times or lags in computer programming by enabling processes to continue to run in the background of the primary application.
• For example, it may prevent a cursor from taking the time to load, allowing a user to complete actions within the application more quickly.

How does asynchronous programming work?

• When you use asynchronous programming, you create an event loop. This is a process that waits for and dispatches events or messages, called a promise, in a program.
• As part of the event loop, you may create a callback, which allows the event loop to supply information from the program to another piece of code, typically the primary function of the program.
• During that time, the application can perform other tasks while you await the program. This allows potentially taxing tasks to run without forcing the user to wait for their completion. 
• Await is a function or operation of many programming languages that allows asynchronous programming.

Benefits of asynchronous programming:

• It provides an improved user experience.
• It helps improve an application's performance.
• It's applicable in a broad range of programming languages. 
• It can improve the speed of a program.
• It creates efficient memory management.
