Avoid using this feature in new projects. HTML wrapper methods exist only for backwards compatibility. Use DOM APIs to create elements instead. This feature may be a candidate for removal from web standards or browsers.
Consider using the following features instead: DOM.
O mtodo sup() cria um elemento HTML <sup> que faz com que uma string seja exibida como sobrescrito.
str.sup()
Uma string contendo um elemento HTML <sup>.
O mtodo sup() cria uma string dentro de uma tag <sup>: "<sup>str</sup>"
sub() e sup()O exemplo a seguir usa os mtodos sub() e sup() para formatar uma string:
var superText = "superscript";
var supText = "supscript";
console.log("This is what a " + superText.sup() + " looks like.");
// "This is what a <sup>superscript</sup> looks like."
console.log("This is what a " + supText.sup() + " looks like.");
// "This is what a <sup>supscript</sup> looks like."
