obj is not a meaningful name, please go for something related to what is stored in this variable

Yes, it should be referring to a single post. I have changed it.

you're already iterating through your array, why do you need a second loop?

you can combine the 2 lines in 1 and declare the variable as const

try to use a path instead of the full url. this way it would work both on your local computer and in the production server.

in a real application you'd display some error where the user can see it.
maybe you could populate some text in a div that has error CSS styling, and make it visible.
| var postContainer = document.querySelector('.post-container'); | ||
| data.map(post => { | ||
| if (post.hasOwnProperty("blogpost")) { | ||
| var postDiv = document.createElement("div"); |

try to use const or let instead of var, as var ofter behaves in mysterious ways
