How to render a Object in React?
Data is an object so directly we can't use map on that, so use Object.keys or Object.entries to get the array first, then use map on that to create ui items.
Using Object.keys:
_renderObject(){
return Object.keys(ObjectTest).map(obj, i) => {
return (
<div>
id is: {ObjectTest[obj].id} ;
name is: {ObjectTest[obj].name}
</div>
)
})
}
Using Object.entries:
const ObjectTest = {
1: {
id : 1,
name:'ABC'
},
3: {
id: 3,
name:'DEF'
}
}
class App extends React.Component{
_renderObject(){
return Object.entries(ObjectTest).map(([key, value], i) => {
return (
<div key={key}>
id is: {value.id} ;
name is: {value.name}
</div>
)
})
}
render(){
return(
<div>
{this._renderObject()}
</div>
)
}
}
ReactDOM.render(<App/>, document.getElementById('app'))<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>

all these mappings... Bruh. Use "pre" tag with JSON.stringify
<pre>
{JSON.stringify(yourdataobject, null, 2)}
</pre>
const ObjectTest = {
1: {
id : 1,
name:'ABC'
},
3: {
id: 3,
name:'DEF'
}
}
render(){
return (
<div>
Object.keys(ObjectTest).map( (key)=> {
return <div>
<span>"Id is:"{key}<span>
<span>"Name is:"{ObjectTest[key].name}<span>
</div>
})
</div>
)
}
