1. How to compare two JSON have the same properties without order?
a. var obj1 = { name: "Person 1", age:5 };
b. var obj2 = { age:5, name: "Person 1"};

=>Answer.
var obj1 = { name: "Person 1", age:5 };
var obj2 = { age :5 , name:"Person 1"};

//fetch properties
let prop1 = Object.getOwnPropertyNames(obj1);
let prop2 = Object.getOwnPropertyNames(obj2);

//will loop in for loop, iterating the list of properties and then comparing their values
for (let i = 0; i <obj1.length; i++) {
    let obj = obj1[i];
	    
		    if (obj1[prop] !== obj2[prop]) {
			        console.log("false");
					    }
						  }
						    console.log("true");

2. Use the rest countries' API URL ->http://restcountries.rest/v3/all and display all the country flags in the console.

=>Answer.
var request=new XMLHttpRequest();

request.open('GET','https://restcountries.com/v3.1/all',true)

request.send();

request.onload=function() {

    var data=JSON.parse(this.response)
    console.log(data)
    console.log(data[0].flag)
    console.log(data[0].flags.png)
    console.log(data[0].flags.svg)
    

    // for loop

    for(i=0;i<data.length;i++){
      console.log(data[i].flag)
      console.log(data[i].flags.png)
      console.log(data[i].flags.svg)
    }
}

3. Use the same rest countries and print all countries name, region, sub region and population

var request=new XMLHttpRequest();

request.open('GET','https://restcountries.com/v3.1/all',true)

request.send();

request.onload=function() {

    var data=JSON.parse(this.response)
    console.log(data)
    console.log(data[0].name)
    console.log(data[0].name.common)
    console.log(data[0].capital)
    console.log(data[0].region)
    console.log(data[0].subregion)
    console.log(data[0].population)
    
    

    // for loop

    for(i=0;i<data.length;i++) {
      console.log(data[i].name.common)
      console.log(data[i].capital)
      console.log(data[i].region)
      console.log(data[i].subregion)
      console.log(data[i].population)
      
}
}
