How to pass String from Java to JS?

Question

JavaScript

I am using JsBridge library to pass data from android activity to webview with js.
I am sending string via method

webView.send("Hi");

In the console I see the following

I/chromium: [INFO:CONSOLE(1)] "{"data":"Hi"}", source: file:///android_asset/demo.html (1)

How can I get "Hello" from data in demo.html as a text resource?
