 🔒 Best Practices for Secure Coding
 1️⃣ Never store sensitive information in immutable strings 🚫
+
 2️⃣ Understand how Garbage Collection (GC) works in your programming language 🧐
+
 3️⃣ Use Secret Managers or Vaults to store sensitive information 🔐
+
 4️⃣ Use prebuilt Secure Strings to handle sensitive information
+
 Java: Use GuardedString (from Java's security libraries)
+
 C#: Use SecureString to handle sensitive data securely 
+
 5️⃣ When no prebuilt library exists, store passwords in char[] and overwrite the array after usage to ensure it doesn't linger in memory.
