fold issues with ES5

[nogo10]

As shown on stackoverflow question ES6 arrow function " => " works fine with observable.fold(seed, f)

const stream = Bacon.sequentially(100, ["Hello", "world"])    
stream.log("stream")
const concatenated = stream.fold("", (a,b) => a + b)
concatenated.log("concatenated")

However in strict ES5 syntax:

var stream = Bacon.sequentially(100, ["Hello", "world"]);
stream.log("stream");
var concatenated = stream.fold("", function (a,b){ a + b});

it doesn't work results in 'undefined' value on console

You're missing a return statement :)

Because you've missed a return.

const concatenated = stream.fold("", (a,b) => a + b)

In es5 is actually

var concatenated = stream.fold("", function (a,b){ return a + b});
