Create a webpack to bundlify all the JS files

[harshit-bs]

Before jumping into opening a PR I'd like to know about a few key things to create the necessary changes.
for webpack config -
entry point, loader(babel ig) and test paths

if babel -
presets to be added

considering I'll run webpack only for building the project.
Please let me know. Thanks in advance!
