console.log('Data'+data);
What causes the variation in console output?

This scenario occurs because when you utilize the + operator, it converts the array into a string, combines it with 'Items', and then passes the resulting string as the first parameter. As a result, the array is converted to [object Object],[object Object], leading to the output of
Items[object Object],[object Object]If you place the array in the second parameter instead, and since there are no format specifiers (%s, %o, etc...) in the first parameter, many browsers will attempt to format the array using "optimal useful formatting" and display it alongside the string. It's important to note that this behavior is not required by the specification, as the Printer function is implementation-dependent.
One effective method is by utilizing console.table. Additionally, remember that using console.log("Items" + array) will display "Items [object object]," while console.log("Items", array) will show the content of the array.
Whenever you combine a variable with a string, the output will be displayed in the format of the string.
'Items',array
In the example above, since there is no concatenation being used, the items print normally. But if you were to use "Items"+array, the entire statement would be printed as a string.
