Modular polyfill for substr(-1) for IE browsers.
Credit goes to MDN for the polyfill code and to mulllhausen for a bugfix. This repo is here so npm and bower can include it easily.
bower install substr-polyfill
Use -S to save to bower.json
bower install -S substr-polyfill
npm install substr-polyfill
To save to package.json
npm install substr-polyfill --save
