This is super succicnt, and here I was doing this all the time like a total schmo…

…

JS Result
EDIT ON
function randomNum(minVal, maxVal) {
do {
r = Math.random();
} while (r == 1);
return minVal+Math.floor(r*(maxVal+1-minVal));
}
var coolwords = new Array();
coolwords[0] = “robot”;
coolwords[1] = “inferno”;
coolwords[2] = “giga”;
coolwords[3] = “infinity”;
coolwords[4] = “pow”;
coolwords[5] = “smash”;
coolwords[6] = “boom”;
coolwords[7] = “crunch”;
coolwords[8] = “robot”;
coolwords[9] = “inferno”;

document.body.innerHTML = coolwords[randomNum(0, coolwords.length-1)];

Thank you! As a total newbie developer this actually helped me complete my first (extremely simple and crude) website. Now to understand the Math command… :)

Need some front-end development training?
