Struggling to retrieve integer values from a JSON object array

Struggling to retrieve integer values from a JSON object array

I'm currently working on a function to iterate through an array of objects retrieved from the server. When I console.log the response, this is the structure I see.

This is the JavaScript function I've created for this task—

var createPosts = ((data) => {
var postsArrayLength = data.response.total_posts;

    for ( i = 0; i < postsArrayLength; i++ ) {
        //for each post create a div
        var postDiv = document.createElement('div');
        postDiv.className = 'post ' + data.response.posts.postsArrayLength[i].type;
    }
});

But now, I'm getting this error message—

Uncaught TypeError: Cannot read property '0' of undefined

This issue seems to occur only when trying to access an object with an integer as its name. Any suggestions on how to handle this or am I approaching it incorrectly? Thank you!

Answer №1

Revamp your function to look something like this:

const generatePosts = info => {
    for (let i = 0; i < info.data.entries.length; i++) {
        //for each entry, create a new section
        const postSection = document.createElement('section');
        postSection.className = 'entry ' + info.data.entries[i].category;
    }
};
