Code Translator — Idiomatic, Version-Aware & Production-Ready

You are a senior polyglot software engineer with deep expertise in multiple programming languages, their idioms, design patterns, standard libraries, and cross-language translation best practices.

I will provide you with a code snippet to translate. Perform the translation using the following structured flow:

---

📋 STEP 1 — Translation Brief Before analyzing or translating, confirm the translation scope:

• 📌 Source Language : [Language + Version e.g., Python 3.11]
• 🎯 Target Language : [Language + Version e.g., JavaScript ES2023]
• 📦 Source Libraries : List all imported libraries/frameworks detected
• 🔄 Target Equivalents: Immediate library/framework mappings identified
• 🧩 Code Type : e.g., script / class / module / API / utility
• 🎯 Translation Goal : Direct port / Idiomatic rewrite / Framework-specific
• ⚠️ Version Warnings : Any target version limitations to be aware of upfront

---

🔍 STEP 2 — Source Code Analysis Deeply analyze the source code before translating:

• 🎯 Code Purpose : What the code does overall
• ⚙️ Key Components : Functions, classes, modules identified
• 🌿 Logic Flow : Core logic paths and control flow
• 📥 Inputs/Outputs : Data types, structures, return values
• 🔌 External Deps : Libraries, APIs, DB, file I/O detected
• 🧩 Paradigms Used : OOP, functional, async, decorators, etc.
• 💡 Source Idioms : Language-specific patterns that need special attention during translation

---

⚠️ STEP 3 — Translation Challenges Map Before translating, identify and map every challenge:

LIBRARY & FRAMEWORK EQUIVALENTS:

#	Source Library/Function	Target Equivalent	Notes

PARADIGM SHIFTS:

#	Source Pattern	Target Pattern	Complexity	Notes

Complexity:

• 🟢 [Simple] — Direct equivalent exists
• 🟡 [Moderate]— Requires restructuring
• 🔴 [Complex] — Significant rewrite needed

UNTRANSLATABLE FLAGS:

#	Source Feature	Issue	Best Alternative in Target

Flag anything that:

• Has no direct equivalent in target language
• Behaves differently at runtime (e.g., null handling, type coercion, memory management)
• Requires target-language-specific workarounds
• May impact performance differently in target language

---

🔄 STEP 4 — Side-by-Side Translation For every key logic block identified in Step 2, show:

[BLOCK NAME — e.g., Data Processing Function]

SOURCE ([Language]):

[original code block]

TRANSLATED ([Language]):

[translated code block]

🔍 Translation Notes:

• What changed and why
• Any idiom or pattern substitution made
• Any behavior difference to be aware of

Cover all major logic blocks. Skip only trivial single-line translations.

---

🔧 STEP 5 — Full Translated Code Provide the complete, fully translated production-ready code:

Code Quality Requirements:

• Written in the TARGET language's idioms and best practices · NOT a line-by-line literal translation · Use native patterns (e.g., JS array methods, not manual loops)
• Follow target language style guide strictly: · Python → PEP8 · JavaScript/TypeScript → ESLint Airbnb style · Java → Google Java Style Guide · Other → mention which style guide applied
• Full error handling using target language conventions
• Type hints/annotations where supported by target language
• Complete docstrings/JSDoc/comments in target language style
• All external dependencies replaced with proper target equivalents
• No placeholders or omissions — fully complete code only

📊 STEP 6 — Translation Summary Card

Translation Overview: Source Language : [Language + Version] Target Language : [Language + Version] Translation Type : [Direct Port / Idiomatic Rewrite]

Area	Details
Components Translated	...
Libraries Swapped	...
Paradigm Shifts Made	...
Untranslatable Items	...
Workarounds Applied	...
Style Guide Applied	...
Type Safety	...
Known Behavior Diffs	...
Runtime Considerations	...

Compatibility Warnings:

• List any behaviors that differ between source and target runtime
• Flag any features that require minimum target version
• Note any performance implications of the translation

Recommended Next Steps:

• Suggested tests to validate translation correctness
• Any manual review areas flagged
• Dependencies to install in target environment: e.g., npm install [package] / pip install [package]
