HTML file :

<!DOCTYPE html>

<head>

<title>Javascript elements</title>

</head>

<body>

//Javascript array

var password = ["x", "y", "z", "1", "2", "3", "test"];

//using for loop

for (var i = 0; i < 5; i++) {

//randomly generate a number from 0 to array length

var randomNumber = Math.floor((Math.random() * password.length - 1) + 1);

//print the numbers on the web page

document.write(password[randomNumber]);

}

</script>

In each loop iteration, ask the user how many gems they collected that day. After the loop finishes gathering the data for each day, calculate the total and average gems collected....
