The definition of the command it seems like there ' s no difference between the two syntaxes. If We look at the definitions of the commands

During the introduction to nodejs, nodejs focuses on its asynchronous IO. In the fs module, nodejs provides two read/write modes: asynchronous and synchronous. I. opening analysis The file system module is a simple packaged standard POSIX file I/O operation method set. You can obtain this module by calling require ("fs. All methods in the file system module have asynchronous and synchronous versions. (1) T
