💥 Context in JavaScript: How to Stop Losing this in 2025

Still getting weird bugs when your method runs inside a timer or event? It’s almost always about this.

Here’s how to avoid it — clean, modern, and battle-tested:
✅ Use arrow functions for guaranteed context
✅ Bind once in the constructor
✅ Use closure-based factories — skip this altogether
✅ Add a runtime check to fail fast when context is wrong
✅ Avoid self = this unless you love 2010

Context bugs are silent killers. These patterns will save your logic and your weekends.
