+// INFO: Different Ways to Print Output in JavaScript
+
+// 1. console.log()
+//    - Prints messages to the console with a newline.
 console.log("Hello");
-process.stdout.write("hey");
 
+// 2. process.stdout.write()
+//    - Writes output without adding a newline (Node.js specific).
+process.stdout.write("hey\n"); // Added \n for newline
+
+// 3. console.table()
+//    - Displays objects or arrays in a table format for better readability.
 console.table({ city: "Islamabad" });
+
+// 4. console.warn()
+//    - Prints warning messages, usually highlighted in the console.
 console.warn({ city: "newCity" });
+
+/*
+Note:
+- In browsers, `console.log()`, `console.warn()`, and `console.table()` are commonly used.
+- `process.stdout.write()` is primarily used in Node.js environments.
