Sure, here are five examples of Node.js syntax:

1. Defining a variable:

   const message = "Hello, World!";

1. Using built-in modules:

   const fs = require('fs');

1. Creating a function:

   function greet(name) {
       console.log(`Hello, ${name}!`);
   }

1. Using arrow function:

   const add = (a, b) => {
       return a + b;
   };

1. Using asynchronous file reading:

   const fs = require('fs');

   fs.readFile('example.txt', 'utf8', (err, data) => {
       if (err) throw err;
       console.log(data);
   });

These examples demonstrate basic Node.js syntax for variable declaration, module import, function creation, arrow functions, and asynchronous file reading using the fs module.
