Event Loop vs Poll
Developers should learn event loops when building applications that require high concurrency and responsiveness, such as web servers, real-time systems, or GUI-based software, to avoid blocking operations and improve performance meets developers should use polling in scenarios where event-driven mechanisms are unavailable, unreliable, or too complex, such as in simple embedded systems, legacy applications, or when interfacing with hardware that lacks interrupt support. Here's our take.
Event Loop
Developers should learn event loops when building applications that require high concurrency and responsiveness, such as web servers, real-time systems, or GUI-based software, to avoid blocking operations and improve performance
Event Loop
Nice PickDevelopers should learn event loops when building applications that require high concurrency and responsiveness, such as web servers, real-time systems, or GUI-based software, to avoid blocking operations and improve performance
Pros
- +It's essential for mastering asynchronous programming in languages like JavaScript (Node
- +Related to: asynchronous-programming, non-blocking-io
Cons
- -Specific tradeoffs depend on your use case
Poll
Developers should use polling in scenarios where event-driven mechanisms are unavailable, unreliable, or too complex, such as in simple embedded systems, legacy applications, or when interfacing with hardware that lacks interrupt support
Pros
- +It is also useful for periodic tasks like checking for updates, monitoring system health, or implementing timeouts in network communications, though it can lead to inefficiencies like high CPU usage or latency if not optimized properly
- +Related to: event-driven-programming, interrupt-handling
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Event Loop if: You want it's essential for mastering asynchronous programming in languages like javascript (node and can live with specific tradeoffs depend on your use case.
Use Poll if: You prioritize it is also useful for periodic tasks like checking for updates, monitoring system health, or implementing timeouts in network communications, though it can lead to inefficiencies like high cpu usage or latency if not optimized properly over what Event Loop offers.
