When an inexperienced person studies PHP and JavaScript, what year or later should the book be published?

I heard that programming languages change their specifications in a few years.
If it is a book, how many years or later should I choose?

Why don't you choose the one that was published this year or last year?

Also, I haven't come across a difficult and easy-to-understand book in either language.

It would be good if you read the preface of the book to see if the scope of the description of the book and the audience fit you.In addition to the content, there are other preferences such as style, so if you actually pick up a book at a bookstore or library and check the contents before purchasing it, you won't fail.
Also, if there are many typographical errors, the learning will not progress, so it would be good to check if there are any incorrect tables before purchasing.

Besides books, some people say that video learning is easier to understand, so there is a way to incorporate video learning.(Personally, I think it's good to use it together.)

In this industry, people say dog year, mouse year, and so on, so if you want to follow language specifications and instructions with "always up to date", you have to rely on the web instead of books.In addition, it is quite common for the actual processing system to focus on stability and not follow the latest version of the language specification.Therefore, it is not recommended to keep up with the latest.It's impossible to learn without moving your hands just by reading a book, so I recommend that you prepare an actual processing system in some way.You may want to look for a processing version that you have confirmed can be used under contract with a rental server company, or a book that corresponds to the processing version you have introduced into your virtual machine.
(Can be the other way around, introduce a processing version tailored to your book)

The book that was good for Oira is good for you, but it's not like that, so I can't recommend a book. Shopping list questions are also deprecated by SO's policy.

# PHP is the back javascript at the front desk, and the roles are completely different, so if you study at the same time, you will be confused.At first, I think it's better to focus on one or the other.
