Script: Transpose, Find and Save - google-apps-script

Question

I have some data containing, Dates, Usernames and an average percent that i want to save in a certain way. My problem is that the order of the usernames can change depending on if new ones are added. I therefore need to "find" a specific username and then save the percentage data in the correct column.
I have found some code that partially helps me save the data that i need. But i could use some help in the "find" the corresponding username and save it in a certain Column part.
function save() {
var sss = SpreadsheetApp.getActive();
var ss = sss.getSheetByName('Result');
var range = ss.getRange('B1:B10');
var data = range.getValues();
var tss = SpreadsheetApp.getActive();
var ts = tss.getSheetByName('Archive');
ts.getRange(ts.getLastRow()+1, 1,data[0].length,data.length)
.setValues(Object.keys(data[0]).map ( function (columnNumber) {
return data.map( function (row) {
return row[columnNumber];
});
}));
}
Basically from this:
To a result that looks like this:
Thank you for your assistance.

Alright for anyone out there that may have a similar problem, this is what i ended up with.
function extractAttendance() {
var currentSheet = SpreadsheetApp.getActive();
var attendanceTab = currentSheet.getSheetByName('Data_Filtered');
var userData = attendanceTab.getRange('B1:B').getValues();
var percentageData = attendanceTab.getRange('I1:I').getValues();
var archiveTab = currentSheet.getSheetByName('Archive');
var existingUsersRow = archiveTab.getRange('1:1');
var newRowNumber = archiveTab.getLastRow() + 1;
archiveTab.getRange(newRowNumber, 1).setValue(new Date());
for (var i = 1; i < userData.length; i++) {
var user = userData[i][0];
if (user === '') {
continue;
}
var existingUsers = existingUsersRow.getValues()[0];
var exists = false;
var existingColumnNumber = -1;
for (var j = 0; j < existingUsers.length; j++) {
if (existingUsers[j] === user) {
exists = true;
existingColumnNumber = j + 1;
break;
}
}
if (exists) {
archiveTab.getRange(newRowNumber, existingColumnNumber).setValue(percentageData[i]);
} else {
var newColumnNumber = archiveTab.getLastColumn() + 1;
archiveTab.getRange(1, newColumnNumber).setValue(user);
archiveTab.getRange(newRowNumber, newColumnNumber).setValue(percentageData[i]);
}
}
}

It might be easier to implement your desired functionality through looping rather than through mapping.
The following code retrieves all users ad their percentage data in ‘Result’ and transfers the data (in the format you desire) to "Archive" with the percentages data pasted with the corresponding timestamp into the first empty row.
function save() {
var sss = SpreadsheetApp.getActive();
var ss = sss.getSheetByName('Result');
var range = ss.getRange('B1:B');
var percentageRange = ss.getRange('G1:G');
var userData = range.getValues();
var percentageData = percentageRange.getValues();
var tss = SpreadsheetApp.getActive();
var ts = tss.getSheetByName('Archive');
var userRow=1;
var percentageRow=(ts.getLastRow()+1)
for(var i=0; i<=userData.length; i++)
{
{
var j=(i+2);
ts.getRange(userRow, j).setValue(userData[i])
ts.getRange(percentageRow, 1).setValue(new Date())
ts.getRange(percentageRow, j).setValue(percentageData[i])
}
}
}
