--description--
Random numbers are useful for creating random behavior.
JavaScript has a Math.random()
function that generates a random decimal number between 0
(inclusive) and 1
(exclusive). Thus Math.random()
can return a 0
but never return a 1
.
Note: Like Storing Values with the Assignment Operator, all function calls will be resolved before the return
executes, so we can return
the value of the Math.random()
function.
--instructions--
Change randomFraction
to return a random number instead of returning 0
.
--hints--
randomFraction
should return a random number.
assert(typeof randomFraction() === 'number');
The number returned by randomFraction
should be a decimal.
assert((randomFraction() + '').match(/\./g));
You should be using Math.random
to generate the random decimal number.
assert(__helpers.removeJSComments(code).match(/Math\.random/g).length >= 0);

--after-user-code--
(function(){return randomFraction();})();
--seed-contents--
function randomFraction() {
// Only change code below this line
return 0;
// Only change code above this line
}
--solutions--
function randomFraction() {
return Math.random();
}
