React: TypeError: nextDeps.join is not a function

[rockfight]

I am getting this error while using hooks.

This is related code.

const market = useContext(MarketContext);
useEffect(() => {

  nav.items[1] = {
                 name: 'Market',
                url: '/market',
                icon: 'icon-speedometer',
                badge: {
                       variant: market == "Live" ? "primary" : "secondary",
                text: market,
           }
  };

}, market)

Can you provide a codesandbox sample instead?

You probably meant to pass [market] rather than market as useEffect argument.

I'll close but I'm sending https://github.com/facebook/react/pull/15018 to add a warning for this.
