A button




When  the user clicks the button the DOM gets changed.



let b = document.createElement('button');
b.innerText = 'click me';
b.onclick = ()=>{
  document.body.append('Hello world');
}
document.body.append(b);



let b = document.createElement('button');
b.innerText = 'click me';
b.onclick = ()=>{
  document.body.append('Hello World!');
}
document.body.append(b);





An input box and a button




The user can change the text that gets echoed.



let i = document.createElement('input');
i.value = 'New York ';
let b = document.createElement('button');
b.innerText = 'click me';
b.onclick = ()=>{
  document.body.append(i.value);
}
document.body.append(i,b);



let i = document.createElement('input');
i.value = 'New York ';
let b = document.createElement('button');
b.innerText = 'click me';
b.onclick = ()=>{
  document.body.append(i.value);
  document.body.append(i.value);
}
document.body.append(i,b);
