Running JavaScript Files
12// hello.js console.log('Hello, Node.js!');
When you execute a JavaScript file with Node.js, you are telling Node.js to read the file, interpret its contents, and run any code written inside. The process starts when you type the node command followed by the filename in your terminal. Node.js loads the specified file, parses the JavaScript code, and executes it line by line in a Node environment. In the example above, Node.js finds the console.log statement and prints the message to your terminal. Once all code in the file finishes running, Node.js ends the process.
How does Node.js handle errors when running scripts?
Node.js handles errors during script execution by printing error messages to the console. If your code throws an error, Node.js describes the error type, the message, and where it occurred in your file. You can learn more by reading about Node.js error handling in the official documentation.
