Not 2013 as it references books published in 2018. This is an update to an older article. The first comment (dated 2013) cites a reference to "Javascript: The Good Parts," which isn't even mentioned in the article. I'm not sure how many times it has been updated, but the most recent update is five days ago, according to the date stamp at the top of the article.
Some of the book recommendations seem outdated, such as Effective JavaScript, which was published in 2015, no use of any of ES6+ features. They help a lot. For modern JavaScript I'm really liking Manning Book's The Joy of JavaScript, a MEAP.
