I'm relatively new in developing with React. I'm currently working on a Commodities Market Ticker. I'm using fetch() to get and render data from JSON API. Here's how the JSON looks:
[
{
Symbol: "BIT:COM",
Ticker: "BIT",
Name: "Bitumen",
Country: "commodity",
Date: "2020-09-30T00:00:00",

},

}
]
If you want to see the full JSON: https://api.tradingeconomics.com/markets/commodities/?c=guest:guest&format=json
This is how I render the data :
import React, {Component} from "react";
import List from './components/list'
class App extends Component{
state = {
data: []
}
componentDidMount() {
fetch('https://api.tradingeconomics.com/markets/commodities/?c=guest:guest&format=json')
.then(res => res.json())
.then((data) => {
this.setState({data: data})
})
.catch(console.log)
}
render() {
return (
<div className={'App'}>
<List data={this.state.data}/>
</div>
)
}
}
export default App;
And here's how I get the data:
import React from "react";
const List = ({ data }) => {
return (
<div>
<h1>Commodities</h1>
{data.map((value) => (
<div>
<h5>Name: {value.Name}</h5>
<h5>Ticker: {value.Ticker}</h5>
<h5>High: {value.day_high}</h5>
<h5>Low: {value.day_low}</h5>
<h5>Unit: {value.unit}</h5>
<hr/>
</div>
))}
</div>
)
}
export default List;
My question is, How to get the first data? Let's say that I want to show Ticker, Name and Date only from "BIT:COM". With my code now it's show all the data. Thank you in advanced.
