I'm developing a Node.js application that needs to interact with the file system. Please navigate to the 'Manipulating Files' section on nodejs.org/learn. Specifically, I want to understand how to read a file, how to write to a file, and how to work with folders (directories). Additionally, what is the purpose of 'file descriptors' in Node.js, and how can I find information about them?
Navigate to 'https://nodejs.org/en/learn'. Click on the 'Manipulating Files' section in the left navigation menu (ID 258). Click on the 'Reading files with Node.js' link (ID 270) and identify how to read a file. Navigate back to the 'Manipulating Files' section. Click on the 'Writing files with Node.js' link (ID 274) and identify how to write to a file. Navigate back to the 'Manipulating Files' section. Click on the 'Working with folders in Node.js' link (ID 278) and identify how to work with folders. Navigate back to the 'Manipulating Files' section. Click on the 'Working with file descriptors in Node.js' link (ID 266) and identify the purpose of file descriptors. Synthesize all collected information into a concise answer.
The agent successfully navigates to the 'Manipulating Files' section. The agent successfully navigates to 'Reading files with Node.js' and explains how to read a file (e.g., using `fs.readFile()` or streams). The agent successfully navigates to 'Writing files with Node.js' and explains how to write to a file (e.g., using `fs.writeFile()` or streams). The agent successfully navigates to 'Working with folders in Node.js' and explains how to work with folders (e.g., creating, reading, deleting directories). The agent successfully navigates to 'Working with file descriptors in Node.js' and explains the purpose of file descriptors (e.g., an abstract handle to a resource like a file or socket). All collected information is synthesized into a concise answer.
