Pull request #82 ships code incompatible with some browsers

[vpicone]

#82 uses template literals which aren't supported in ie 11. Regular string concatenation should be used or the code should be compiled to es5 before being shipped.

This was discovered when my build script failed due to es6 code being discovered in one of my deps.

Failed to compile.

Failed to minify the code from this file:

relevant info from the link:

Some third-party packages don't compile their code to ES5 before publishing to npm. This often causes problems in the ecosystem because neither browsers (except for most modern versions) nor some tools currently support all ES6 features. We recommend to publish code on npm as ES5 at least for a few more years.

This also happens in a few other locations touched by #82, once it's fixed in one the error crops up in the others.

Thanks for letting us know, I opened #89 to resolve.
