Compile a JavaScript file into a single executable application:
```console
$ echo 'console.log(`Hello, ${process.argv[2]}!`);' > hello.js
$ cp $(command -v node) hello
$ npx postject hello NODE_JS_CODE hello.js \
--sentinel-fuse NODE_JS_FUSE_fce680ab2cc467b6e072b8b5df1996b2
$ npx postject hello NODE_JS_CODE hello.js \
--sentinel-fuse NODE_JS_FUSE_fce680ab2cc467b6e072b8b5df1996b2 \
--macho-segment-name NODE_JS
$ ./hello world
Hello, world!
```
