I am a newbie in NodeJS, my background is Swift.

When facing forEach, I wonder if it would create a reference cycle?

const array = [1, 3, 2, 4]
arrach.forEach(function(element) {
    doSomething(element)
})

function doSomething(number) {
    // ...
}

In Swift, the code above will create a reference cycle since the closure has referenced to a function in self, which is doSomething. Is this also a case in NodeJS?

Regards,

`arrach.forEach(function(element, index, array) ...` – Aikon Mogwai Jul 10 '17 at 11:32
@Aikon, what do you mean? – quanguyen Jul 11 '17 at 02:26
Js has the same cycle as Swift. `function doSmth(e) { console.log(e); }; [1,2,3].forEach(doSmth);`. – Aikon Mogwai Jul 11 '17 at 06:36
What should I do to `solve` this cycle? – quanguyen Jul 11 '17 at 07:27
