javascript - computerChoice is not a function error -

-

so having problems making rock, paper , scissors game. keep getting error "typeerror: computerchoice not function" can see why happening, don't know how fix it.

heres code; 

var userchoice = prompt("do chose rock, paper or scissors?"); var computerchoice = math.random();   console.log(computerchoice)  if (computerchoice < 0.33)  {     computerchoice("rock"); }  else if (computerchoice < 0.66) {     computerchoice("paper"); }  else (computerchoice < 1)  {     computerchoice("scissors"); }

ive been told since var isn't function problem, how fix it. tried var computerchoice = function (math.random()); still didn't work.

thanks whoever can me! :)

you have assign value variable. here's code.
