Is a book from 2015 too old to learn from?

Hello all. I have in my possession a book on JavaScript coding, but it's from 2015. Could I learn from this book, or should I seek something more up to date? Thanks for any help.

IMO - you can definitely learn the basics from it, but be sure to UPDATE your knowledge with current developments.

ES6 was a major milestone \~ mid June 2015. If your book (u mentioned 2015) has included ES6 thats great, if not, make sure you follow the releases post 2015 especially ES6 (being the biggest one), with subsequent releases adding on new features.
