Add content to a new open window

When You want to open new tab/window (depends on Your browser configuration defaults):

output="Hello, World!";
window.open().document.write(output);

When output is an Object and You want get JSON, for example (also can generate any type of document, even image encoded in Base64)

output = ({a:1,b:'2'});
window.open('data:application/json;' + (window.btoa?'base64,'+btoa(JSON.stringify(output)):JSON.stringify(output)));

Update

Google Chrome (60.0.3112.90) block this code:

Not allowed to navigate top frame to data URL: data:application/json;base64,eyJhIjoxLCJiIjoiMiJ9

When You want to append some data to existing page

output="<h1>Hello, World!</h1>";
window.open('output.html').document.body.innerHTML += output;

output="Hello, World!";
window.open('about:blank').document.body.innerText += output;
