How to find out which table in TempDB consumed most spaces?

how do I concat the name of the array object to extract info

Barbara

i am creating a search function and inoredr to loop throught the array i have to do some sort of concatenating like

" general_array [0].column_name_array[1] "

instead of specifing the name of the objeck like this

" general_array [0].ledger_num "

general_array  = [
  RowDataPacket {
    id: 1,
    ledger_num: 'VM364',
    file_num: 'VM364',
    agereement_date: 2022-07-21T18:30:00.000Z,
    client_name: 'sam',
    status: 'UNSETTLED'
  }
.
.
]

function search( searchInput1 , general_array ) {
  let column_name_array = [`ledger_num`, `file_num`, `agrreement_date`,`status`]

  if(general_array [0].column_name_array[1] == some_variable){
  consol.log("found")
 }
}
