What are the trade-offs between using arrow functions everywhere to avoid this confusion vs using regular functions with explicit binding?

Arrow functions simplify code by automatically capturing this from the surrounding scope, reducing this-related bugs and eliminating the need for .bind() calls. However, they are not ideal for prototype methods (where dynamic this is needed), and using them in classes (as class fields) creates per-instance functions, potentially increasing memory usage. Regular functions with explicit binding provide more control and are better suited for prototype methods or when you need to leverage call/apply/bind. The trade-off is between convenience and flexibility/memory efficiency.
