fs.writeFileSync in nodeJs

fs.writeFileSync is a method in Node.js used to write data to a file synchronously. It takes three parameters: the file path to write data to, the data to write, and an optional parameter for encoding. If the file already exists, it will be replaced. If the file does not exist, it will be created. The method returns undefined if the operation is successful, or throws an error if there is a problem.
