Why doesn't this condition work?

Question

React

There is some object in coin.symbol, it can be 'BTC' or 'XRP' so that's why this condition does not work

const
                coinsymbol = coin.symbol == 'BTC' || 'ETH' ? coin.symbol + 'ETH' : coin.symbol + 'USD'

I draw the chart like this

<TradingViewWidget
                                            symbol={coinsymbol}
                                            theme={Themes.DARK}
                                            locale="fr"
                                            autosize
                                        />

but for any object it adds + 'eth'

Answer 1

coinsymbol = coin.symbol == 'BTC' || coin.symbol == 'ETH' ? coin.symbol + 'ETH' : coin.symbol + 'USD'
