Featured image for Best JavaScript Conferences 2020

Today you are either a programmer or hear about development every day. Even the oldest generation will no longer be able to avoid these conversations. After all, much is said about this on the Internet and on TV. You also may not be a developer, but you definitely have at least one such friend or acquaintance.

But if you are a front-end or back-end specialist, then the code lives inside you. Most likely, your head is filled with questions about improving testing, rising performance, fixing any bugs and so on. This is a problem for every developer. Even if you are involved with JavaScript, which today is considered the best programming language.

You always have a few options. The first is to figure it out all alone. But no one does. The second is to find tips and answers on thematic forums. The third is to attend several JavaSript conferences and discuss all issues with colleagues live, and ideally, apply new skills immediately.

It is difficult to deny that the latter option will be more effective. Therefore, it remains only to choose a conference. A list of the best JavaScript events of 2020 can be found below. Mark the dates on the calendar!
