Convert your es5 code to es6, using basic transforms. Right now what happens is that simple anonymous functions are converted to arrow syntax.

function(a,b,c) {
   a = b + c;
   return a + 2;
}

gets converted to

(a,b,c) => {a = b + c; return a + 2;}

Using

Just call node index.js <file.js> to transpile to sysout

> node index.js test.js

alternatively, write directly to same infile

> cat test.js | node index.js | tee test.js
