Google Script: forEach to Array

Question

I'm trying to push the returned values from forEach to an array.

Right now results are returned individually in the Logger like

result 1 result 2

That's what I want, I just don't know how to get those results back to a single array that I can use outside of the forEach function (as this function is part of a larger one).

Any tips? I looked HERE and attempted to work from that below. The other results I found here were about PHP, which I don't understand.

urls.forEach(function(urlTest) {
    var htmls = UrlFetchApp.fetch(urlTest).getContentText();
    var reg = /text1boldblack\"\>U(.*?)\<\/div/g;
    var reg2 = /text1boldblack\"\>|\<\/div/g;
    var extract = htmls.match(reg);
    var string = String(extract);
    var listDivName = string.replace(/text1boldblack\"\>|\<\/div/g,'');

    var array = [];
    for (var i = 0; i < listDivName.length; ++i) {
    array.push(i);
    Logger.log(array);
    }

Below is an example of what Logger.log(array); currently returns which is obviously more than the two results I was expecting.

"I'm trying to push the returned values from forEach to an array."

ForEach has no return value, but map has!

Map acts like forEach but the return value creates a new array.

const resultArray = urls.map(function(urlTest) {
    var htmls = UrlFetchApp.fetch(urlTest).getContentText();
    var reg = /text1boldblack\"\>U(.*?)\<\/div/g;
    var reg2 = /text1boldblack\"\>|\<\/div/g;
    var extract = htmls.match(reg);
    var string = String(extract);
    var listDivName = string.replace(/text1boldblack\"\>|\<\/div/g,'');

    return listDivName;
}

// do sth with the array:
console.log(resultArray);
