Does the function isPrime have a property known as answers and another property key named value? If isPrime.answers[value] yields [value] after the execution of the function, does [value] become both a variable outside of its original function scope and simultaneously a property key within the answers object?
function isPrime(value) {
if (!isPrime.answers) {
isPrime.answers = {};
}
if (isPrime.answers[value] !== undefined) {
return isPrime.answers[value];
}
var prime = value !== 1; // 1 is not a prime
for (var i = 2; i < value; i++) {
if (value % i === 0) {
prime = false;
break;
}
}
return isPrime.answers[value] = prime;
}
