In 2013, when Craig Buckler studied the best programming languages, he found that demand for JavaScript grew faster than any other language. As the network develops, JavaScript's status continues to improve, becoming a formal programming language that needs to be carefully learned and mastered, rather than just a piece of code that you don't know much about how it works, or just hidden behind jQuery and other libraries. language. At SitePoint, we have been following this trend, listening to readers’ feedback, and planning a flexible learning path to improve your JavaScript skills. Now it's time to familiarize you with this language that will likely become a key partner in HTML and CSS in the future. Communication with experts
