Working with some data from a JSON/Array from a known video game. I'm close to creating a new array with ONLY the localized name, but can't quite get it right. What am I missing:

const endpoint = './heroes-org.json'
let heroes = []
let renamed = []

fetch(endpoint)
  .then(text => text.json())
  .then(data => heroes.push(...data.result.heroes))
  .then(() => {
    for(i = 0; i < heroes.length; i++){
        // renamed += heroes[i].localized_name
        //heroes.map(function){
        //}
        setTimeout(function(){
            console.log(renamed)
        }, 2000)
    }})

The map function was an idea to get rid of the unnecessary keys of each array element.

Also, if I just console log heroes from within the chrome console shows me this:

Doesn't seem quite right. Why is my array separated into 0-99 etc.?

I ultimately want to end up with just 1 array containing all the 115 heroes' names.
