one explanation :
The console.log("QTY\tITEM\t\t\tTOTAL"); line is used to print the header of the receipt, which includes the titles for each column: "QTY" for quantity, "ITEM" for item name, and "TOTAL" for total cost.
Here's a breakdown of what each part of the string does:
\t: This is an escape sequence representing a tab character. It adds spacing between the columns. "QTY": This is the title for the quantity column. "ITEM": This is the title for the item name column. "\t\t\t": This adds extra tabs to provide additional spacing between the item name column and the total column. "TOTAL": This is the title for the total cost column.
