#13 ES5 syntax for utils

[idir]

Summary

Changes proposed in this pull request:

• When we use ESM webpack importer instead of compiled lib in dist, we get issues on web browser that does not understand ES6 syntax such as IE11. Indeed, webpack+babel ignore node_modules and don't transpile these utils to ES5 before usage. Therefore it caused on our side issues for users who do checkout with fat arrow syntax. Furthermore, I have tested solutions such as upgrading to Babel 7 + babel.config.js instead of babelrc + are-you-es5 package. This latest does not consider index.js file used to generate the lib in the dist folder.
• This pull request solve the issue by rewritting utils in ES5 syntax

Tested scenarios

• Not applied. It does not impact utils usage.

Fixed issue: #13
