IMA.js Babel 6 Polyfill

Provides a polyfill for IE9 and IE10 to fix super-constructor calls in the Babel 6 runtime, addressing transpilation issues that affect applications using Babel 6 class inheritance on legacy Internet Explorer versions. Version 0.12.0 is the latest stable release, but the package is in maintenance mode and not actively developed. It is part of the IMA.js ecosystem and intended for use with IMA.js applications, though it can be used as a standalone fix. Alternatives include using Babel 7's @babel/polyfill or core-js for broader IE support.
