In index2.js,
The tip does not change from "Brighten up your mood" to "You are doing great!" when a text that is okay is passed after one that triggers the thresholds.
Steps to reproduce:
Type "I am sad." in the text box and upload.
Type "I am happy!" in the textbox and upload afterwards
The root directory is cluttered with unnecessary scripts and files
Here are the files not needed:
index.js
bundle.js
reference
speechRecog.js
testing.js
watson-speech.js
(maybe) the package json files
