Why is this js code so slow?
- by SpiderPig
This code takes 3 seconds on Chrome and 6s on Firefox.
If I write the code in Java and run it under Java 7.0 it takes only 10ms.
Chrome's JS engine is usually very fast. Why is it so slow here?
btw. this code is just for testing. I know it's not very practical way to write a fibonacci function
fib = function(n) {
if (n < 2) {
return n;
} else {
return fib(n - 1) + fib(n - 2);
}
};
console.log(fib(32));
