es-shimses-string-html-methods 
An ES-spec-compliant shim/polyfill/replacement for the Annex B String.prototype HTML methods that works as far down as ES3
This package implements the es-shim API “multi” interface. It works in an ES3-supported environment and complies with the spec.
Because the String.prototype HTML methods depend on a receiver (the this value), the main export in each subdirectory takes the string to operate on as the first argument.
The main export of the package itself is simply an array of the available directory names. It’s sole intended use is for build tooling and testing.
Supported methods
String.prototype.anchorString.prototype.bigString.prototype.blinkString.prototype.boldString.prototype.fixedString.prototype.fontcolorString.prototype.fontsizeString.prototype.italicsString.prototype.linkString.prototype.smallString.prototype.strikeString.prototype.subString.prototype.sup
