Is there a way to retrieve object data without using the map JS function?

Currently, I am delving into a project involving React, Redux, and JS. The tutorial I am following incorporates a dummy object within the redux store as illustrated below.

const initState = {
    posts:[
       [
        {id: '1', title: 'Fire', body: 'Squirtle Laid an Egg'},
        {id: '2', title: 'Land', body: 'Charmander Laid an Eg'},
        {id: '3', title: 'More Land', body: 'a Helix Fossil was Found'}
       ]
    ]
}

During my learning process, I noticed that the producer of the tutorial leverages posts.map() to extract data from the object. However, I am curious if there is a way to retrieve this data without utilizing the map function. I attempted the following:

<p>{posts[0].id}</p> 

Unfortunately, this triggered an error message:

Uncaught TypeError: Cannot read property '0' of undefined

Could someone guide me on the correct way to access only the first id value of this object?

    

Answer №1

In order to access the first element of posts, you must ensure that you have included the correct wrapping object. Use the following syntax: initState.posts[0][0].id

Answer №2

Remember that the variable posts[0] contains an array consisting of 3 objects. Since it's nested, you'll need to access the id property by calling posts[0][0].id
