Import/Export Correctness Linting

Build a linting setup that enforces ES module import/export correctness for a small JavaScript codebase.

Capabilities

Valid modules pass

• src/valid/math.js exports named helpers (for example add and multiply) with no default export, and src/valid/index.js imports those names without errors. @test

Named vs default validation

• Linting src/invalid/bad-named.js fails because it requests a named import (e.g., total) that src/valid/math.js does not export.
• Linting src/invalid/bad-default.js fails because it default-imports src/valid/math.js, which should be treated as a named-exports-only module. @test

Path and self-guardrails

• Linting src/invalid/missing-path.js fails because the referenced module path cannot be resolved using the configured extensions.
• Linting src/invalid/self-cycle.js fails because the module directly imports itself (including via a relative alias). @test

Implementation

• Provide an ESLint configuration that enables import/export validation for src/**/*.js files and enforces the behaviors above.
• Include runnable lint commands that target the sample files in src/valid and src/invalid.
