- You can obtain data form the server using a fetch call.
- In these examples you will be getting data from /worldl.json this is a list of 195 countries in json format
- The program snippet shows the name of country 42.
- Change it so it shows the name of country 50.
fetch('/worldl.json')
.then((r)=>r.json())
.then((r)=>{
let tgt = r[42];
document.body.innerHTML = tgt.name;
});
fetch('/worldl.json')
.then((r)=>r.json())
.then((r)=>{
let tgt = r[50];
document.body.innerHTML = tgt.name;
});
