This usually happens in older JavaScript engines or environments the place the required updates have not been applied. For example, trying to make use of `await` straight inside a module’s high stage in an older browser or Node.js model will set off this error. A workaround includes wrapping the code inside an instantly invoked async perform expression.
Assist for this performance simplifies asynchronous code on the high stage of modules, eradicating the necessity for instantly invoked async features. This results in cleaner and extra readable code, notably when coping with module initialization involving asynchronous operations like fetching assets or establishing connections. The historic context includes the evolution of JavaScript’s asynchronous dealing with; older variations lacked this function, requiring extra advanced workarounds. Fashionable environments embracing the most recent JavaScript requirements usually present this functionality.
