Javascript setTimeout Recursive [duplicate]

Question

Consider this :

function some_function(){
  axios.get(...)
  .then(x=>{//handle})
  .catch(e=>{//handle})
  .then(()=>{
    setTimeout(()=>{
      some_function();
    },5000);
}

I don't care aboout cancelation, I just care if this is gonna blow the stack up.

Not just setTimeout, also the asynchronous network request and the promise then calls prevent this from blowing up the stack. — Bergi

No, it won't cause the stack to grow. setTimeout() callback functions are called from the main event loop asynchronously, not from your function. Your function returns immediately after you make the axios.get() call (since that's also asynchronous, it doesn't wait for it, either).

I though so. But using console.trace(), traces all the way back to the first call. So that was my main concerne.

I wasn't familiar with that function. Despite what MDN says, I think that's a trace of scopes, not stack frames. Closures allow scopes to persist after popping the stack.
