Memory Management Guide

Memory management is a critical aspect of software development that ensures efficient use of system resources. Here's a concise overview of key concepts and best practices:

Key Concepts

• Stack vs Heap:
  📌 Stack memory is automatically managed for local variables, while heap memory requires manual allocation and deallocation.

  

• Garbage Collection:
  🧹 In languages like JavaScript, garbage collection automatically reclaims unused memory. Learn more about memory optimization techniques.

  

• Reference Counting:
  📊 Used in languages like Python to track object usage.

  

Best Practices

1. Avoid Memory Leaks
   ⚠️ Use tools like Valgrind for detection.
2. Optimize Data Structures
   📈 Choose efficient structures (e.g., arrays over linked lists).
3. Use Smart Pointers
   🔗 In C++, prefer std::unique_ptr or std::shared_ptr for automatic resource management.

Tools & Techniques

• Memory Profilers:
  📊 Tools like gperftools (Linux) or VisualVM (Java) help analyze memory usage.
• Object Pooling:
  🧱 Reuse objects to reduce allocation overhead.

Common Pitfalls

• ❌ Overusing global variables
• ❌ Not releasing unused resources
• ❌ Ignoring memory alignment optimizations
