I like using the helpful ReactJS. It is a JavaScript library for user interfaces.
I never heard of it.
How about Sencha Touch which is another JavaScript. 
Never heard of it either; i'm a basic computer user.
Well Sencha Touch is a JavaScript library for user interfaces on the web and to develop apps.
I'm curious i will do some research.
If you do then also look up Ext JS.  That is another one but used to cross platform web apps like Ajax or DOM.
Ok, thank you for the useful information.
Then the next step is Google Chrome which is used to serve as the platform for the app.
Do you make money creating apps ?
