# Grammarly Data Handling ## Overview Handle large documents, text chunking, and data pipelines for Grammarly API. The API accepts max 100,000 characters (4 MB) with a minimum of 30 words. ## Instructions ### Step 1: Text Chunking ```typescript function chunkText(text: string, maxChars = 90000): string[] { if (text.length <= maxChars) return [text]; const paragraphs = text.split('\n\n'); const chunks: string[] = []; let current = ''; for (const p of paragraphs) { if ((current + '\n\n' + p).length > maxChars && current) { chunks.push(current); current = p; } else { current = current ? current + '\n\n' + p : p; } } if (current) chunks.push(current); return chunks; } ``` ### Step 2: Aggregate Scores Across Chunks ```typescript function aggregateScores(scores: any[]): any { const avg = (arr: number[]) => arr.reduce((a, b) => a + b, 0) / arr.length; return { overallScore: Math.round(avg(scores.map(s => s.overallScore))), correctness: Math.round(avg(scores.map(s => s.correctness))), clarity: Math.round(avg(scores.map(s => s.clarity))), engagement: Math.round(avg(scores.map(s => s.engagement))), tone: Math.round(avg(scores.map(s => s.tone))), chunkCount: scores.length, }; } ``` ### Step 3: File Processing Pipeline ```typescript import fs from 'fs'; async function scoreFile(filePath: string, token: string) { const text = fs.readFileSync(filePath, 'utf-8'); const chunks = chunkText(text); const...
