How to determine that current instance of Node.js is running on Termux?

Preferably fully from the JS.

Assuming you don't have access to an ENV that has a platform var (because then you could just check that), you could write a function that was something along the lines of

    if (process.platform === 'android') {
        try {
            const fs = require('fs');
            // Check for Termux-specific directory
            return fs.existsSync('/data/data/com.termux/files/usr');
        } catch (error) {
            return false;
        }
    }

to check for termux!

Wouldn't this false-positive in other emulator when Termux is installed?
