5.1.2 function call mechanismIn the previous study, we mentioned the concept of "call function" many times. The so-called function, that is, the execution of control of the program from the caller (a function) to the called function, while passing parameters to the called function to pass data, and then the program into the called function inside, execute the code in the function definition to obtain the re

The call to call and the invocation of a reference are questions that almost all major languages can relate to, and I'll talk about my understanding of the invocation of values in C # and the invocation of a reference.1. General understanding of invocation of values in C # and invocation of reference If the passed parameter is a primitive type (int,float, etc.) or struct (struct), then it is a valu

execute a piece of code within a certain amount of time, and you cannot execute multiple pieces of code simultaneously, so there is a task queue in JavaScript, and the tasks to be performed are queued in sequence, The set delay time is the time to add the current task to the task queue. If no task is currently executing, the code that is added to the task queue executes immediately, and if there is currently an executing code snippet, then the newly joined task is performed only when the code s
