+# debugLogger
+
+> A simple environment-aware logging utility for client and server scripts.
+
+**Use case:**  
+In one of my projects, we wanted to log messages only in non-production environments without commenting them out each time. This small helper does that elegantly.
+
+```javascript
+/**
+ * debugLogger(message, level)
+ * Logs only if NOT in production.
+ * Level can be 'info', 'warn', or 'error'
+ */
+var debugLogger = (function() {
+  var isProd = gs.getProperty('instance_name') === 'prod-instance'; // change per your instance
+  return function(msg, level) {
+    if (isProd) return;
+    level = level || 'info';
+    gs[level]('[DEBUG] ' + msg);
+  };
+})();
+
+// Example usage:
+debugLogger('Checking record count...', 'info');
