Bug 247437

// input.js
print (
    String(function * () {})
);
__________________________

Hello,

The space between `function` and `*` should be retained in the result of toString of the generator function, but JSC removes all the space between them.

Running the input.js with JSC prints:

---
$ jsc input.js
function* () {}
---

while other engines behave like:

---
# V8 (used console.log)
$ node input.js
function * () {}

# GraalJS
$ js input.js
function * () {}
---
