LeetCode Code-Gen Dataset — JavaScript

631 rows. Given a problem statement, its input/output examples, and a required algorithm/technique, generate a correct JavaScript solution.

Part of a 4-language collection built from the same source: see the sibling Python, Java, C++, and JavaScript datasets.

Verification

Not execution-verified. There is currently no compiler/runtime harness for this language in the build pipeline (only Python has one). Rows are extracted directly from named solution approaches in doocs/leetcode, a well-maintained community solutions repo, so correctness is likely but not guaranteed. Treat this the way you'd treat any unverified scraped code dataset.

Source

Extracted from doocs/leetcode, which documents multiple named solution approaches per problem (e.g. "Dynamic Programming", "Two Pointers", "Divide and Conquer") -- this is what makes per-row algorithm labeling possible, since the same problem can appear multiple times with a different technique and different code each time.

Fields

Example row

{
  "slug": "house-robber",
  "primary_algorithm": "Dynamic Programming",
  "messages": [
    {"role": "system", "content": "You are a competitive programming assistant..."},
    {"role": "user", "content": "### Problem\n...\n### Algorithm\nDynamic Programming"},
    {"role": "assistant", "content": "```javascript\n...\n```"}
  ]
}

Known gaps

• —SQL/database problems excluded (wrong problem type for a code-execution harness)
• —Design/class problems (LRU Cache, iterators) excluded -- they need a sequence of method calls to test, not a single input -> output check
• —Some Brute Force labels are a fallback where the source didn't name a specific technique for that approach
