• is the fastest and simple and more developer-friendly way to develop web application
• i learned it very fast
• i became able to develop web app alone and very fast

• make it faster (for framework like Cordova)

My opinion is that in the future every platform will support (more than native code) a universal markup/graphic/script language which allow to write one and execute everywhere. But since that moment,

... jQuery family, i love you!
