+**bindNodeCallback** - `bindNodeCallback` is a function that converts a Node.js-style callback function into an Observable.
 
 ```typescript
+import 'zone.js/dist/zone';

+import { CommonModule } from '@angular/common';
+import { bootstrapApplication } from '@angular/platform-browser';
+import { bindNodeCallback  } from 'rxjs/ajax';
+
+// Assume we have a Node.js-style callback function for file reading
+function readFileAsync(filePath: string, callback: (error: Error | null, data: string) => void) {
+  // Some asynchronous file reading logic
+  // Call the callback with the error (if any) and the file data
+  setTimeout(() => {
+    if (filePath === '/path/to/file.txt') {
+      callback(null, 'File content goes here');
+    } else {
+      callback(new Error('File not found'), null);
+    }
