we create an instance of FN with variable a (which is equivalent to copying a FN to object a), just creating it and not executing it, and calling this function fn is object A, so this point is the object, so why is there a user in the object fn? Because you've copied the FN function into object A, using the New keyword is equivalent to copying a copy. In addition to the above, we can also change the point of this by itself, to see the summary of the Call,apply,bind method in JavaScript in deta

Brief introduction Data integration is a key concept in the Data warehouse. The design and implementation of the ETL (data extraction, transformation and loading) process is an extremely important part of the Data Warehouse solution. ETL processes are used to extract business data from multiple sources, clean up data, then integrate the data, and load them into the Data Warehouse database to prepare for data analysis. ETL Process Design Although the actual ETL design and implementation depend

Flexible array Members allow the structure to contain an array of variable sizes. The size of the structure returned by sizeof does not include the memory of the
