Features

✅ Automatic Tail Call Optimization

  • Converts tail-recursive functions to efficient loops at compile time
  • Prevents stack overflow errors
  • Zero runtime overhead
  • Production-ready quality

✅ Comprehensive Support

  • Function declarations and expressions
  • Arrow functions (block and expression forms)
  • Conditional tail calls (ternary operators, if/else statements)
  • Logical expression tail calls (&&, ||)
  • Nested conditions and complex patterns

✅ Developer Experience

  • Full TypeScript support with type definitions
  • Source maps for debugging
  • Configurable optimization via annotations
  • Clean, readable generated code
  • Detailed error messages

Performance

📊 Benchmark Results:

  • Handles 100,000+ iterations without stack overflow
  • Performance near hand-written loops
  • 0-2ms for complex recursive operations
Test Input Unoptimized Optimized Result
Factorial 10,000 ❌ Stack overflow ✅ 0ms Crash prevention
Sum 100,000 ❌ Stack overflow ✅ 1ms Crash prevention
Fibonacci 10,000 ❌ Stack overflow ✅ 2ms Crash prevention

See PERFORMANCE.md for full benchmark results.

Quality Assurance

✅ 100% Test Coverage - 40 comprehensive tests
✅ CI/CD - Automated testing on Node.js 18/20/22
✅ Code Quality - Codecov integration
✅ Type Safety - Full TypeScript definitions

Documentation

Installation

npm install --save-dev js-tail-recursion-opt-plugin

Quick Start

.babelrc

{
  "plugins": ["js-tail-recursion-opt-plugin"]
}

Example:

// Before optimization - causes stack overflow at ~10,000
function factorial(n, acc = 1) {
  if (n <= 1) return acc;
  return factorial(n - 1, n * acc);
}

// After optimization - works for any depth!
factorial(100000); // ✅ No stack overflow!
