Google Apps Script: RegExp g Modifier - google-apps-script

Question

I can't seem to get the "g modifier" in a RegExp to work in a Google script.
When I try to apply it, sometimes I get the error that "ReferenceError: "g" is not defined.". When I remove the /g both regExp.exec and input.match(regExp) work, but only for the first match. Other times, I'll get the /g to work, but it returns null, not even producing the first match. I had attempted a while loop, but I didn't want to slow down this process even more (I'll save optimizing this script for another post once I get it to work as intended).
The short version is, I'm trying to get ALL matches (email addresses) not just the first one. Where do I apply the /g? Should I use another method?
You can see (below) what I've been attempting below.
Any tips? I appreciate any help me understand this and anyone that can show me a better way to approach this. Thanks!
if (colA != "" && colE != processed) {
var html = UrlFetchApp.fetch(colA).getContentText();
//Logger.log(html);
var regExp = new RegExp("[A-z0-9._%+-]+#[A-z0-9.-]+\.[A-z]{2,4}");
var regExp2 = new RegExp("[A-z0-9._%+-]+#[A-z0-9.-]+\.[A-z]{2,4}");
var regExp3 = '[A-z0-9._%+-]+#[A-z0-9.-]+\.[A-z]/g {2,4}';
var regExp4 = '[A-z0-9._%+-]+#[A-z0-9.-]+\.[A-z]{2,4}/g';
var extractTest = html.match(regExp3);
//var extract = regExp.exec(html);
Logger.log(extractTest);
}
You can see the "bigger picture" of it all below.
//TEST
var processed = "YES";
function test() {
var ss = SpreadsheetApp.openById('1E4yUVIpwi00DzjfnXrZSgNFmVjOQbNWewxAiTBHRdD4');
var sheet = ss.getSheetByName('Sheet5');
var currentRow = 2;
var currentColumn = 1;
var numRows = sheet.getLastRow()-1;
var numColumns = 5;
var range = sheet.getRange(currentRow, currentColumn, numRows, numColumns);
var values = range.getValues();
//Logger.log(values);
for (var i = 0; i < numRows; ++i) {
var column = values[i];
var colA = column[0];
var colB = column[1];
var colC = column[2];
var colD = column[3];
var colE = column[4];
if (colA != "" && colE != processed) {
var html = UrlFetchApp.fetch(colA).getContentText();
//Logger.log(html);
var regExp = new RegExp("[A-z0-9._%+-]+#[A-z0-9.-]+\.[A-z]{2,4}");
var regExp2 = new RegExp("[A-z0-9._%+-]+#[A-z0-9.-]+\.[A-z]{2,4}");
var regExp3 = '[A-z0-9._%+-]+#[A-z0-9.-]+\.[A-z]/g {2,4}';
var regExp4 = '[A-z0-9._%+-]+#[A-z0-9.-]+\.[A-z]{2,4}/g';
var extractTest = html.match(regExp3);
//var extract = regExp.exec(html);
Logger.log(extractTest);
}
}
//var destRange = sheet.getRange(currentRow+i,2);
//destRange.setValue(extract);
//var destRange2 = sheet.getRange(currentRow+i,5);
//destRange2.setValue(processed);
SpreadsheetApp.flush();
}

Using the solution provided by #I'-'I (see comments above): var re = /[A-z0-9._%+-]+#[A-z0-9.-]+\.[A-z]{2,4}/g;
