How to make a data array with values and formulas - arrays

Question

I'm trying to alter some code from a tutorial on how to remove duplicate rows from my sheet. The code works great for straight values, but some of my rows have cells with hyperlink formulas that I don't want to lose.
I think I need to make the spreadsheet data as an array, rather than just using getValues. It's been a long time since I've had to make an array, so I'm struggling with the best way to do this. I'll need for loops to populate the array and if statements to either get values or formulas depending on the row.
Here's the remove duplicates code that removes rows if the cell in column A and B match another row:
/**
* Removes duplicate rows from the current sheet.
*/
function removeDuplicates() {
var sheet = SpreadsheetApp.getActiveSheet();
var data = sheet.getDataRange().getValues();
var newData = [];
for (var i in data) {
var row = data[i];
var duplicate = false;
for (var j in newData) {
if(row[0] == newData[j][0] && row[1] == newData[j][1]){
duplicate = true;
}
}
if (!duplicate) {
newData.push(row);
}
}
sheet.clearContents();
sheet.getRange(1, 1, newData.length, newData[0].length).setValues(newData);
}
So instead of just using one line to set the data variable, I need to build the array with values and formulas where appropriate. Otherwise, I lose my hyperlinks. How do I do this?
Edit: This question was solved by using an answer to another question. The questions' contexts are not the same, and the other question did not show up in any of my research, so I believe my question is not a duplicate.

Answer 1

Thanks to the comment by TheMaster, I was able to solve this. Here's the original "Remove Duplicates" tutorial, and here's the question TheMaster directed me to to find the solution.
My final code:
/**
* Removes duplicate rows from the current sheet.
*/
function removeDuplicates() {
var sheet = SpreadsheetApp.getActiveSheet();
var range = sheet.getDataRange();
var newData = [];
var data = range.getValues();
data = range.getFormulas().map(function(e, i) {//i=index of row(e)
return e.map(function(f, j) {//j = index of column(f)
return f === "" ? data[i][j] : f;
});
});
for (var i in data) {
var row = data[i];
var duplicate = false;
for (var j in newData) {
if(row[0] == newData[j][0] && row[1] == newData[j][1]){
duplicate = true;
}
}
if (!duplicate) {
newData.push(row);
}
}
sheet.clearContents();
sheet.getRange(1, 1, newData.length, newData[0].length).setValues(newData);
}
