Pretty straight-forward. See comments inline:
var result = []; // Results will go here
var nowHour = new Date().getHours(); // Get current hour of the day
// Loop from current hour number to 23
for(var i = nowHour; i < 24; i++){
result.push(i + "00"); // Put loop counter into array with "00" next to it
}
console.log(result); // show results
