Can I Simplify my Script in Google Sheets? - google-sheets

Question

I have built a Google Sheet using scrips to automatically timestamp certain events on the sheet upon edit.
Two of the timers are built to time just the first edit of two particular cells:
function onEdit() {
var s = SpreadsheetApp.getActiveSheet();
if( s.getName() == "SUBARU" ) {
var r = s.getActiveCell();
if( r.getColumn() == 3 ) {
var nextCell = r.offset(0, 19);
if( nextCell.getValue() === '' )
nextCell.setValue(new Date());
}
}
}
Two additional timers time any instance two other cells are edited:
function onEdit() {
var s = SpreadsheetApp.getActiveSheet();
if( s.getName() == "SUBARU" ) {
var r = s.getActiveCell();
if( r.getColumn() == 9 ) {
var nextCell = r.offset(0, 15);
nextCell.setValue(new Date());
}
}
}
And three other timers time when three specific entries happen in one particular cell:
function onEdit() {
var s = SpreadsheetApp.getActiveSheet();
if( s.getName() == "SUBARU" ) {
var r = s.getActiveCell();
if( r.getColumn() == 5 ) {
var nextCell = r.offset(0, 20);
if( r.getValue() === "3 - Menu Ready")
nextCell.setValue(new Date()).setNumberFormat('dd-MM-yyyy HH:mm:ss');
}
}
}
My problem is that I have seven scripts per sheet, and 4 sheets using the scripts (so 28 total scripts running). My Google quote is 30 scripts running at the same time. Can anyone think of ways I can simplify these scripts to run quicker or combine any so that I have fewer running at any given time?
Any help would be greatly appreciated!!!

Answer 1

My suggestion for this is to group all logic into one "onEdit" function.
Here's my code approach/suggestion to handle it:
if(s.getName() == "SUBARU") {
//put the logic to handle sheet SUBARU
} else if(s.getName() == "ABC") {
//put the logic to handle sheet ABC
} else if(s.getName() == "DEF") {
//put the logic to handle sheet DEF
}
