We can only speculate what the future will be, but it's quite certain that it will include JavaScript. For quite some time JavaScript may have been underestimated and underused (or rather overused in the wrong ways), but every day we witness new uses of JavaScript in much more interesting and creative ways. Where they once wrote simple one-liners, often embedded in-line in HTML tag attributes (such as onclick), developers nowadays ship sophisticated, well-designed and architected, extensible applications, and libraries. JavaScript is indeed taken seriously and developers are starting to rediscover and enjoy its unique object-oriented features more and more.

Once listed in the "nice to have" sections of job postings, these days the knowledge of JavaScript is a yes/no factor when it comes to hiring web developers. Common job interview questions you can hear today include: "Is JavaScript an object-oriented language? Good. Now how do you implement inheritance in JavaScript?" After reading this book, you'll be prepared to ace your JavaScript job interview and even impress your interviewers with some bits that maybe they didn't know.
