var num1 = prompt("Please type a number");
var num2 = prompt("Please type another number");
var message = "<h1>Math with the numbers " + num1 + " and " + num2 + "</h1>";
num1 = parseFloat(num1);
num2 = parseFloat(num2);
if((Number.isFinite(num1) && Number.isFinite(num2)) && (num1 !==0 && num2 !== 0)) {
alert("Let's do some math!");
message +=
`
${num1} + ${num2} = ${num1 + num2} <br>
${num1} * ${num2} = ${num1 * num2} <br>
${num1} / ${num2} = ${num1 / num2} <br>
${num1} - ${num2} = ${num1 - num2}
`;
document.write(message);
} else {
alert('Please insert two numbers, and dont use 0');
}
does it right to use the document.write inside the if statement?
