Can I escape html special chars in javascript?

Question

I want to display a text to HTML by a javascript function. How can I escape html special chars in JS? Is there an API ?

Answer 1

function escapeHtml(html){
  var text = document.createTextNode(html);
  var p = document.createElement('p');
  p.appendChild(text);
  return p.innerHTML;
}

// Escape while typing & print result
document.querySelector('input').addEventListener('input', e => {
  console.clear();
  console.log( escapeHtml(e.target.value) );
});
