I saw that you could use the content option, but im not really sure how to go about that right now I have something like:
swal({title: 'hello', text: 'hello ${<strong>{name}</strong>}', icon: 'success' })
From the GitHub Issues, you should set a content and insert the text within it:
var name = "Stack Overflow";
var content = document.createElement('div');
content.innerHTML = 'Hello <strong>'+ name +'</strong>';
swal({
title: 'Hello',
content: content,
icon: "success",
})
