How to invoke a simple GET Request using XHR without ANY fancy JavaScript Framework (React, Vue, Angular etc)

Source code:

function getData() {
  var xhttp = new XMLHttpRequest();
  var targetUrl = "https://pokeapi.co/api/v2/pokemon/pikachu";
  
  xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      document.getElementById("demo").innerHTML =
      this.responseText;
    }else if (this.status){
		document.getElementById("demo").innerHTML = "Can not access: " + targetUrl 
			+ " 
 Response: " + this.status + " " + this.responseText;
	}else{
		document.getElementById("demo").innerHTML = "Loading... ";
	}
  };
  
  xhttp.open("GET", targetUrl, true);
  xhttp.send();
}
