forEach is a code smell

This JavaScript-focused article presents the opinion that the forEach method is often a 'code smell,' indicating potential performance issues. It explains that forEach requires a new function allocation on each call, which can be inefficient, particularly with nested loops or closures. The author contrasts forEach with traditional for or while loops, suggesting the latter are often more performant, while acknowledging forEach isn't always bad but warrants careful consideration.
