Second Language syndrome

I was reading a book the other day. ProgramClerk, which mentioned that some programmers had second language syndrome-it was easy to learn the third and fourth languages, but the second language would have killed them. At that time, I was sure that I had this problem, because I had always wanted to know the Java language, but I was reluctant to start. I had never known why it was so difficult to start. Now I am suddenly enlightened. Soon after I read this book, the book was very thin and I began to plan to break this syndrome. The first target language was Javascript. Will my second language syndrome be good when I can use JavaScript to survive? The day of the test will soon come.
