3. Is JavaScript becoming obsolete?

First invented in 1995, JavaScript is certainly a language that’s been around for quite a long time. This long existence may lead some to think that it’s becoming obsolete, but as of writing, that couldn’t be further from the truth.

JavaScript continues to grow in popularity today. It is still worth learning in 2023, considering it ranks as one of the most used languages worldwide. It is also the only coding language that is usually native to web browsers.

4. How much does it cost to learn JavaScript?

Learning JavaScript can cost you nothing. With enough determination, you can get through some of the best free JavaScript courses on this list and finish with enough knowledge to get you started on your career. However, if you would prefer a more structured course where you are taken through things step-by-step, you can consider a Udemy course or a coding Bootcamp.

Udemy courses often go on sale for anywhere from six to twenty dollars. Unfortunately, when at full price, Udemy courses can cost around $50 to $200. Prices truly depend on the courses’ creators, but you can always look at ratings to help you decide. Udemy also often provides a 30-day money-back guarantee. Coding bootcamps, on the other hand, cost around $12,000 on average but are very flexible when it comes to repayment options.
