T.DEMO3 (111)                        ///test whether to support multiple methods      This is very important, JS call C # method, many methods of C # are multi-method definition: If not supported, success may not be called.

Script test Results

Jint supports params, does not support default parameters, does not support multiple methods,

Jurassic supports params, does not support default parameters, supports multiple methods,

The Nlua supports params, supports default parameters, supports multiple methods,

The clearscript supports params, supports default parameters, supports multiple methods,

Clearscript is tested using the "Jscriptengine" method, and without using the V8 engine, mono seems to be unable to use it, and there is no test.

In terms of performance, it's probably

Nlua or Jurassic > Clearscript or Jint

It's probably just a matter of testing a few string operations and regular expression loops, and testing is not exhaustive.

Clearscript in the use of JS RegExp time performance is the best, but added a C # var rr = T.regex (' [a-z]+ ') after the performance is very bad, do not know why.

project maintenance aspects.

Nlua or Clearscript or Jint > Jurassic

Nlua or Clearscript or Jint these 3 have been in the maintenance of the update

Jurassic has not been updated for 2 years, but after testing the feeling is very good, compatibility +, performance is also OK,

Compatibility Aspects

Nlua or Jint or Jurassic > Clearscript

Nlua needs to call 2-3 DLLs, multi-platform support: Ios,linux, Windows

Jint Jurassic is a DLL, written in pure C #, compatibility should be OK, Linux has not been tested, but read Mono's documentation, should be supported.

Clearscript use JScript mode only one DLL is enough, but it seems that the system interface is called, cross-platform does not know how, V8 mode needs to call 2-5 DLLs, and V8 engine is written in VS2013. Also need to install VC runtime ... Feel the engine or C # to write better, abnormal capture ah those are more convenient.
