Re: [nodejs]will kilos setTimeout spend too much resourece?
If you pass a function reference to an existing function to setTimeout, and then call this function repeatedly, rather than creating a closure each setTimeout call, that will lower your memory and cpu overhead substantially.

Re: [nodejs]will kilos setTimeout spend too much resourece?
Oh cool! and I found
setTimeout(console.log, 1000, 'hello world')
is much better than
setTimeout(function(){
console.log('hello world');
}, 1000)
