How to split combined string into multiple strings in array?

How can I split this array with commas? I have multiple arrays

[ "LeadershipPress" ]
[ "BusinessLeaderLeadershipPress" ]
[ "LeaderLeadershipPoliticsPress" ]
etc.

scraper.scrapeListingPages('article.article', (item) => { 
    var categories = $(item).find('a[rel = "category tag"]').text().split();
    console.log(categories);
    categories.forEach(function(i){
       $(i).find('a[rel = "category tag"]')
       console.log(i);
    })
});

Right now my output in the console is

Array [ "BusinessLeaderLeadershipPress" ]
BusinessLeaderLeadershipPress

I want to split the categories into an array with commas without having to use separator, limits or regex because I have multiple random arrays.

Is there a way I can use a forEach or for loop to accomplish this?

The result I want is [ "Business, Leader, Leadership, Press" ]

Thanks

A simple approach using for-loop with algorithm taking Consideration that string starts with Uppercase: Looping through characters of the string if char is not UPPERCASE accumelate chars to variable word, until encounter Uppercase letter, then push it in res Array.

const string = "BusinessLeaderLeadershipPress";
let i = 1;
let character = "";
let word = string[0];
const res = [];
while (i <= string.length) {
  character = string.charAt(i);
  if (character == character.toUpperCase()) {
    res.push(word);
    word = character;
  } else {
    word += character;
  }
  i++;
}
console.log(res); //['Business', 'Leader', 'Leadership', 'Press']

You could split a string with a look ahead for an uppercase letter.

const
    string = 'BusinessLeaderLeadershipPress',
    result = string.split(/(?=[A-Z])/);

console.log(result);
