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]): ```[source language] [original code block] ``` TRANSLATED ([Language]): ```[target 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] --- Here is my code to translate: Source Language : [SPECIFY SOURCE LANGUAGE + VERSION] Target Language : [SPECIFY TARGET LANGUAGE + VERSION] [PASTE YOUR CODE HERE]
