I understand what you're saying.

My guideline in this is that JSValue must be avoided as much as possible, 
to be used only in case of absolute need.

Once more, the purpose is to make Pascal run in the browser. 
Not to make every possible Javascript construct possible in Pascal.

Some Javascript APIs make heavy use of the Javascript paradigm, and there
finding a suitable pascal equivalent is difficult. But by and large, I find
this limited. The typical Javascript program does not use a typed array.
(some notable exceptions are WebGL and maybe some image manipulations or
cryptographic stuff)
