</ul><p>The topics and features listed above are not always present in a JS developer's daily routine (and even more so in other languages), but it's important to be aware of them. First, the approaches covered in this course are not specific to JavaScript. Knowing them will make it much easier for you to switch to other languages. Secondly, working with functions will significantly boost your programming skills.</p>
