**Purpose**: Test script for MCP (Model Context Protocol) debugger smoke tests, providing a minimal JavaScript example for validating debugger functionality including breakpoints, stepping, and variable inspection.
**Key Components**:
- `main()` function (L8-16): Core test function that performs a simple variable swap operation
- Initializes two variables `a=1, b=2` (L9-10)
- Logs initial state (L11)
- Performs destructuring assignment swap `[a, b] = [b, a]` (L14)
- Logs final state (L15)
- Function invocation (L18): Executes main() to run the test
**Architecture**:
- Uses ES6 module syntax with `export function`
- Executable Node.js script (shebang L1)
- Mirrors equivalent Python implementation for cross-language debugger testing
- Designed specifically for breakpoint placement at L14 to inspect variables in initial state
**Dependencies**: None (pure JavaScript with Node.js console API)
**Test Strategy**: The swap operation provides predictable before/after states ideal for debugger validation, with strategic breakpoint positioning to examine variable values during execution flow.
