## Overview

Integrate code written in different programming languages to leverage their unique strengths and ecosystems.

## When to Use

- Performance-critical code in C/C++/Rust
- ML models in Python from other languages
- Legacy system integration
- Leveraging language-specific libraries
- Microservices polyglot architecture

## Quick Start

Minimal working example:

```cpp
// addon.cc
#include <node.h>

namespace demo {

using v8::FunctionCallbackInfo;
using v8::Isolate;
using v8::Local;
using v8::Object;
using v8::String;
using v8::Value;
using v8::Number;

void Add(const FunctionCallbackInfo<Value>& args) {
  Isolate* isolate = args.GetIsolate();

  if (args.Length() < 2) {
    isolate->ThrowException(v8::Exception::TypeError(
        String::NewFromUtf8(isolate, "Wrong number of arguments")));
    return;
  }

  if (!args[0]->IsNumber() || !args[1]->IsNumber()) {
    isolate->ThrowException(v8::Exception::TypeError(
        String::NewFromUtf8(isolate, "Arguments must be numbers")));
// ... (see reference guides for full implementation)
```

## Best Practices

### ✅ DO

- Use appropriate IPC mechanism
- Handle serialization carefully
- Implement proper error handling
- Consider performance overhead
- Use type-safe interfaces
- Document integration points

### ❌ DON'T

- Pass complex objects across boundaries
- Ignore memory management
- Skip error handling
- Use blocking calls in async code
