Synchronous File Operations
NodeJS also provides synchronous versions of file operations, such as fs.readFileSync()
and fs.writeFileSync()
, which block the execution thread until the operation completes. While synchronous operations may be suitable for certain use cases, they can potentially block the event loop and impact the overall performance of the application, especially in I/O-bound scenarios.
How to read and write files in Node JS ?

(File System), offer various methods for performing file operations such as reading from files, writing to files, and manipulating file metadata. Let’s explore how to read and write files in NodeJS.
