How to superscript character in node.js

Question

does anyone know how to create a superscript character in node.js? I am trying to superscript '®':

let tm = '®'; 
let tm = tm.sup();

However, this returns <sup>®</sup>

Can someone help?

Thanks in advance!

Unfortunately, you can't. You can display some superscript unicode characters (Ex. ¹²³⁴⁵⁶⁷⁸⁹⁰⁺⁻), but '®'(\u00AE) does not have a superscript version.

Node.js does not support text styling itself. With terminal support, you can add modifiers / colors / background colors but not superscript. Please check chalk if you are interested.

Please note the String.prototype.sup() method is designed for HTML page, that's why it will wrap the text with <sup> tag. Also, it is deprecated and removed from the Web standard. It should not be used any more.
