How to use Promise.all with Axios?

Question

    Promise.all(purchaseOrderUpdate.map((purchaseOrder) => {
      return axiosInstance.put(CreatePOUrl + "/" + purchaseOrder.id.toString() + '?correlationId=1', purchaseOrder)
      .then(response => {
        console.log("say 1st")
      })
    }))
    console.log("say last")

I thought by returning the axiosInstance, it is returning a list of promises which should all be resolved before "say last" is printed.

Thanks

Promise.all is itself a promise, so you would still need to either await it, or console.log in it's .then:

Promise.all(purchaseOrderUpdate.map((purchaseOrder) => {
  return axiosInstance.put(CreatePOUrl + "/" + purchaseOrder.id.toString() + '?correlationId=1', purchaseOrder)
  .then(response => {
    console.log("say 1st")
  })
})).then(() => {
    console.log("say last")
});
