If server-side programming languages like C or PHP are utilized, program code is usually processed sequentially. This means that a server does not start implementing a new instruction in code until the previous instruction has been executed and has delivered a result.
In this case, one speaks of asynchronous processing. The execution of further codes is curbed until the current process has finished. This leads to significant delays in complex operations such as accessing the file system, databases, or web services. To overcome this problem you can get the services of renowned NodeJS Development company for Business.
Many programming languages, the runtime environments, and implementations based on these, therefore, support the possibility of performing processes in so-called threads in parallel. These are individual threads of execution as part of a process that can be used to process actions while the rest of the code continues to run.
The disadvantage of this method, multithreading is resource-intensive.
Even though the framework is mainly used for web server programming, it is also used in other areas, such as creating scripts or tools for the command line or developing desktop or real-time applications.
