Answers for "json mock data"

dummy api json

var xhr = new XMLHttpRequest();
xhr.open("GET", "https://reqres.in/api/products/3", true);
xhr.onload = function(){
    console.log(xhr.responseText);
};
xhr.send();

generating test data in api

For API Part: I use "https://www.mockaroo.com/" ==> 
generates multiple format (CSV, JSON, XML, etc)

json placeholder

fetch('https://jsonplaceholder.typicode.com/todos/1')
  .then(response => response.json())
  .then(json => console.log(json))
fetch('https://jsonplaceholder.typicode.com/todos/1')
  .then(response => response.json())
  .then(json => console.log(json))
