How To Detect From Nodejs Which Javascript Engine It Is Running On?

There are now several forks of nodejs and some of them support JavaScript engines other than Google's V8 engine. For my node code to see which JS engine it is running under, what i

Solution 1:

The process object contains a lot of information about the currently running process (in this case, node).

My process.versions for example, contains the current version of V8:

process: {
    versions: {
        http_parser: '2.5.0',
        node: '4.2.4',
        v8: '4.5.103.35',
        uv: '1.7.5',
        zlib: '1.2.8',
        ares: '1.10.1-DEV',
        icu: '56.1',
        modules: '46',
        openssl: '1.0.2e'
    }
}

You should be able to query this object and determine the current engine.
