How arrays of objects are flattenededitElasticsearch has no concept of inner objects. Therefore, it flattens object hierarchies into a simple list of field names and values. For instance, consider the following document: response = client.index(
index: 'my-index-000001',
id: 1,
body: {
group: 'fans',
user: [
{
first: 'John',
last: 'Smith'
},
{
first: 'Alice',
last: 'White'
}
]

How to update array of objects in JavaScript?To update an object in a JavaScript array, you can use findIndex() method for executing each array element and updating the object values accordingly, the for loop method for iterating through an array and updating the specified value, and map() method for mapping the updated value to an object.
How do you update a nested object value?Approach 1: We can create a dummy object to perform operations on it (update properties that we want) then replace the component's state with the updated object. Approach 2: We can pass the old nested object using the spread operator and then override the particular properties of the nested object.
How do you update a nested array of objects in react?The easiest way to update a nested object stored in the Reactjs state is to use the spread operator. I will explain it with several examples. We have a demo Reactjs app that handles a simple personal information form. The form contains the person's information, including address and email address.
