Script Analyzer

Build a utility that analyzes multiple script files and safely extracts interpreter information, handling files that may or may not contain shebang lines.

Requirements

Your implementation should:

1. Accept an array of script content strings as input
2. For each script, safely extract the interpreter path (without the #! prefix) if a shebang exists
3. Return an array of results where each result contains:
   • hasShebang: boolean indicating if a shebang was found
   • interpreter: the interpreter path if found, or null if not found
4. Handle edge cases gracefully without throwing errors for scripts without shebangs

Test Cases

• Given an array with one script containing #!/usr/bin/env node\nconsole.log("test"), returns [{hasShebang: true, interpreter: "/usr/bin/env node"}] @test
• Given an array with one script containing no shebang console.log("test"), returns [{hasShebang: false, interpreter: null}] @test
• Given an array with three scripts where only the second has a shebang #!/bin/bash\necho "hi", returns correct results for all three scripts @test
• Given an empty array, returns an empty array @test
