For example, to send a request to an API called https://jsonplaceholder.typicode.com/users/1, get its HTTP response status code, and then output it to the debugger web console, you can use the Fetch API as follows:Now, use the Response.status property to retrieve the HTTP response status code.^[1].

^[1]

 fetch('https://jsonplaceholder.typicode.com/users/1')
  .then(response=>console.log(response.status)));//=>200

fetch('https://jsonplaceholder.typicode.com/users/100')
  .then(response=>console.log(response.status)));//=>404

 document.querySelector("button").addEventListener("click",()=>{
  fetch('https://jsonplaceholder.typicode.com/users/1')
    .then(response=>console.log(response.status)));//=>200

  fetch('https://jsonplaceholder.typicode.com/users/100')
    .then(response=>console.log(response.status)));//=>404
});

<button>fetch>/button>
