An already existing file can be opened for reading by clicking on open. An opened file will be edited and updated by clicking on save file. All these functions are done with the help of an inbuilt module called FS in Node.js.<\/p>\n<h4><strong><b>The common use of a File system Module are:<\/b><\/strong><\/h4>\n<ul>\n<li>Read Files<\/li>\n<li>Write Files<\/li>\n<li>Append Files<\/li>\n<li>Close Files<\/li>\n<li>Delete Files<\/li>\n<\/ul>\n<p>To include the file system we make use of \u00a0the require() method:<\/p>\n<p>Var fs = require(fs);<\/p>\n<p>To understand better let us learn how to create a file with an example:<\/p>\n<p><strong><b>Step 1: Open Visual Studio Code:<\/b><\/strong><\/p>\n<p>Launch VS Code on your computer.<\/p>\n<p><strong><b>Step 2: Create a New Folder or Open an Existing Project:<\/b><\/strong><\/p>\n<p>Navigate to the directory where you want to create the file, or open an existing project folder in VS Code.<\/p>\n<p><strong><b>Step 3: Open Terminal: <\/b><\/strong><\/p>\n<p>Click on the Terminal menu and select New Terminal to open a new terminal window within VS Code.<\/p>\n<p><strong><b>Step 4: <\/b><\/strong>Navigate to the Directory:<\/p>\n<p>Use the cd command to navigate to the directory where you want to create the file.<\/p>\n<p>For example:<\/p>\n<p><strong><b>bash code<\/b><\/strong><\/p>\n<p>cd path\/to\/your\/directory<\/p>\n<p><strong><b>Step 5: Create a New JavaScript File:<\/b><\/strong><\/p>\n<p>Use the touch command to create a new JavaScript file.
