The following is a code sample using the “highlight” shortcode provided in Hugo. This is server side highlighting and requires Python and Pygments to be installed.
var num1, num2, sum
num1 = prompt("Enter first number")
num2 = prompt("Enter second number")
sum = parseInt(num1) + parseInt(num2) // "+" means "add"
alert("Sum = " + sum) // "+" means combine into a string
