If I ever see this shit in code review I’m flagging it. IIFEs exist to avoid polluting global space in JS - its not something you are often dealing with in modern development. Especially the react example - make a new component, this prevents better readability like a new component or using an inline function.

Additionally for ever developer that hasn’t seen this, they have to look up the run function and try to grasp WTF it is doing. And god forbid someone modifies the run function.
