I have an array of objects with keys that have different names.
let array = [{"obj1": 1, "obj2": 2}, {"obj3": 3}]
I want to be able to display on the front (react-native) the key and the value. I tried doing so with a map and object.entries but it is not working (Error: Objects are not valid as a React child . If you meant to render a collection of children, use an array instead.):
{Object.entries(array).map(([key, val] = entry) => {
return (<Text>{[key, val]}</Text>)
})
How could I display simply in a Text the key and the value of each object?
Try this:
{array.map(item => (
<div>
{Object.entries(item).map(([key, val]) => {
return (
<Text>
{key} = {val}
</Text>
)
})}
</div>
))}
Note: please add keys when using in real application
You should reduce the array, spread the entries, and then flatten. The result will be an array of key-value pairs.
const array = [{ "obj1": 1, "obj2": 2 }, { "obj3": 3 }] const keyValuePairs = array .reduce((pairs, obj) => [...pairs, Object.entries(obj)], []) .flat(); keyValuePairs.forEach(([key, val]) => console.log(key, val));
