Cannot run the instrumented code containing 'const'

[ChangXiaoning]

I am trying to analyze some code that declaring variables using 'const', like:
···
const str='hello world!';
console.log(str);
···
However, when I run the instrumented code, an ReferenceError exception is thrown, telling me the variable is not defined. When I inspect the code, the variable triggering the exception is declared by the reserved key 'const'. I notice there has already been a closed issue:
#41
The issue is to support constant variables.
I want to know how to deal with this problem, except that I manually convert 'const' to var.

we no longer support ES6 const.
