QUESTION 22 OF 30

What are the differences between blocking and non-blocking calls in the context of Node.js?

During an interview as a software engineer, you can anticipate that most questions will be technical or operational. The best way to prepare for this type of interview is to first research the company to understand their programming and the products they produce. Next, you should carefully review the processes you use as a software engineer to develop programs. Having a clear understanding of these will help you respond to any question the interviewer may ask.

"Blocking calls require that the program waits until a non-JavaScript operation is completed before additional JavaScript commands can be executed. Non-blocking calls can execute commands asynchronously at any time. This characteristic results in non-blocking calls having a performance advantage. Node.js uses both of these types of calls."
