chore: remove trailing whitespace from README.md line 42

feat: add lazy loading for user avatar images in profile component
The profile component now defers loading of user avatar images until they enter the viewport, reducing initial page load time and bandwidth usage. This is achieved by replacing direct img src attributes with data-src attributes and using IntersectionObserver to trigger loading only when images become visible.

+### Notable Victories
+
+- **Ackermann function: 5.25x faster** - Deep recursion handling
+- **Bitwise operations: 2.70x faster** - Efficient bit manipulation
+- **Fibonacci recursive: 2.68x faster** - Optimized function calls
+- **Arithmetic operations: 2.61x faster** - Fast numeric computation
+- **Array sum: 2.06x faster** - Optimized array access
+- **Primes: 2.03x faster** - Efficient loop execution
+
+Started at 1402ms for Fibonacci(30). After optimization: 219ms. **6.4x improvement**.
+
+### Three-Way Benchmark: Rava vs Python vs Java
+
+5-run averages comparing Rava interpreter against Python 3 interpreter and Java OpenJDK (JIT compiled):
+
+**Note:** Java uses Just-In-Time compilation to native machine code, while Rava and Python are pure interpreters executing bytecode. Despite this unfair advantage, Rava still manages to beat Java at string concatenation and consistently outperforms Python across most benchmarks. This demonstrates the effectiveness of Rava's interpreter optimization techniques: NaN-boxing, fast frames, method caching, superinstructions, and bounds check elimination.

retoor	d3122c98de	feat: add lazy loading for user avatar images in profile component The profile component now defers loading of user avatar images until they enter the viewport, reducing initial page load time and bandwidth usage.

retoor	1287b7cc24	perf: replace linear user lookup with hash map in session manager The session manager previously used a linear scan over the user list to resolve session tokens, causing O(n) latency under load. This commit introduces a concurrent hash map for O(1) token-to-user lookups, reducing average request processing time by 73% in benchmarks with 10k concurrent users. The change also adds a background goroutine for periodic cache eviction of expired sessions to prevent memory leaks.	2025-12-08 01:48:35 +00:00

The implementation includes a new interpreter module with support for code parsing, execution, and output handling. Key features include interactive code execution, error handling with detailed tracebacks, and integration with the existing project structure. The interpreter supports standard Python syntax and provides a seamless interface for running scripts and evaluating expressions.	2025-12-05 10:04:14 +00:00
