Change a Git Commit Message and Push Safely

Changing a Git commit message creates a new commit ID. Learn when to amend, reword, revert, or reset—and how to update one remote branch with an explicit force-with-lease instead of destructive `push --all -f`.

Fix “Block-Scoped Declarations” in Node.js

This error normally identifies a very old Node.js/V8 parser, not a defective `let` or `const` statement. Diagnose the executable actually running, move the project to a supported Node.js release, reinstall dependencies predictably, and keep modern CommonJS/ESM errors separate.
