First you need to build JSC. Since it is a module in WebKit, you can follow these instructions to get the code and learn how to build it.

https://webkit.org/getting-started/#building-webkit

After the machine setup, you can build JSC as a stand-alone CLI program running

```<path_to_webkit>/Tools/Scripts/build-jsc —release```

It will build jsc into ```<path_to_webkit>/WebKitBuild/Release```
