started. Disadvantages: 1. Poor concurrent processing capability: Because PHP had no threads or process functions at the time, to achieve concurrency, you need to borrow a multi-path model. PHP uses the select model. It is troublesome to implement it. It may be because of the level issues that often occur in my program, leading to missing catch. Let's talk about Python: Advantages: 1. Various crawler frameworks for convenient and efficient download

processNodejs encountered I/O event will create a thread to execute, and then the main thread will continue to execute, therefore, take the action of profile to trigger an I/O event, will immediately execute the action of taking timeline, two actions parallel execution, if each need 1S, then the total time is 1S. After their I/O operations are completed, an event, profile, and timeline are emitted, and the event agent receives and continues to perform the subsequent logic, which is the feature
