I am working on a cli-type application which requires getting data from a third-party API .

with javascript:

const request=new Promiss((resolve, reject)=>{

})

so if I understand, we have an event queue and event loop, and even the loop keeps checking if the async operation is done, if it’s done it fulfils the promises.

now with go lang :

    
func (a *App) VerifyApiKey(apiKey string) bool {

    req, err := http.NewRequest(http.MethodGet, host+"/accounts", nil)
    if err != nil {
        return false
    }
    req.Header.Add("Authorization", "Bearer "+apiKey)
    fmt.Println(apiKey)
    resp, err := http.DefaultClient.Do(req)
    defer resp.Body.Close()
    response, err := io.ReadAll(resp.Body)
    if err != nil {
        return false
    }
    fmt.Println(string(response))
    if resp.StatusCode == http.StatusOK {
        return true
    }
    return false

}

How does this work? go doesn’t have an event queue or loop, it’s based on channels, what’s happening behind the scenes?
