Hi, I work for Hanbit Media, Inc., the largest IT publisher in Korea.
We have translated and published many English programming books here.
I think your book is also very helpful to Korean programmer readers.
Do you have any plan for publication in foreign countries?
If you are willing, I'll let our copyrights manager contact you to discuss the details.
I appreciate your quick response.

console.log(results);
// [{name: "Usain Bolt", race: "100m dash", place: 1}
// {name: "Justin Gatlin", race: "100m dash", place: 2}
// {name: "Asafa Powell", race: "100m dash", place: 3}]
->
results's type is array, so ',' needed.
// [{name: "Usain Bolt", race: "100m dash", place: 1},
// {name: "Justin Gatlin", race: "100m dash", place: 2},
// {name: "Asafa Powell", race: "100m dash", place: 3}]

As a non native speaker there may still be spelling errors or others mistake in the book. If anybody wants to help that would be great.

Template literals were called template strings prior to ES6.. Let’s have a look at what’s changed in the way we interpolate strings in ES6.

I think "prior to ES6" doesn't mean ES1,2,3,5, but "ES6 draft version", is that correct?
ES6 link

could you add the pdf and epub builds to releases and link from readme? ebook novices will have difficulty navigating to the book's content.

Hi @AlbertoMontalesi , big thanks for this book - it meets my needs exactly 🙇‍♂️
I have three suggestions to make it easier to read (I am reading the pdf for now)

1. Apply page headers/footers to show the current chapter
2. Prevent code blocks from overflowing to the next page
3. Tweak the property Title of the pdf downloaded from leanpub - currently it is Final book

best regards
Guntbert

Hi Alberto!

I think that something you can add to this chapter as a warning or whatever you want to call it, is that default parameters are only applied if the arguments is undefined.

Try this:

const printText = (text = 'default') => console.log(text)

printText('Alberto')
// prints ---> 'Alberto'

printText(undefined)
// prints ---> 'default'

printText(false)
// prints ---> false

printText(null)
// prints ---> null

printText('')
// prints ---> ''

So an alternative to this, could be to use the || operator.

Regards!

Hey, great work on the book!

I wanted to mention that in this chapter, you introduce one way of creating functions at the top but not the other. Since there is no section introducing what functions are, it may be worthwhile to introduce it here.

function greeting(name) {
  return "hello " + name;
}

I see it's used in an example further down, but having it at the top could be beneficial for beginners.

// display all our groceries in a p tag, the last one will include all the one from the array **others**
->
It appears that the "**others**" part in the comment of the JavaScript source was just printed out 
while trying to express it in bold in Markdown syntax.

Is that right?
