[link to URL]
String.prototype.small[] DeprecatedString.prototype.strike[]
DeprecatedString.prototype.sub[] DeprecatedString.prototype.sup[] DeprecatedNote that these methods do not check if the string itself contains HTML tags, so it's possible to create invalid HTML:
"".bold[]; //
The only escaping they do is to replace " in the attribute value [for anchor[], fontcolor[],
fontsize[], and link[]] with ".
"foo".anchor['"Hello"']; // foo
Examples
String conversion
It's possible to use String as a more
reliable toString[] alternative, as it works when used on null and undefined. For example:
const nullVar = null;
nullVar.toString[]; // TypeError: nullVar is null
String[nullVar]; // "null"
const undefinedVar = undefined;
undefinedVar.toString[]; // TypeError: undefinedVar is undefined
String[undefinedVar]; // "undefined"
