Essential JavaScript Tools in 2021

JavaScript tools

Old doesn’t mean obsolete, and JavaScript is proof of this. This programming language has been around for more than 2 decades, and it keeps evolving continually. According to SlashData, JavaScript is the most popular programming language worldwide, with over 12.4 million developers using it. Every web developer needs to get their hands on this language and know it from A to Z; otherwise, developing a web app will be nearly impossible. To create great websites with JavaScript, they also need the best tools and frameworks to boost their productivity. And during this article, we will explore the best JavaScript tools in 2021. 

8 Best JavaScript Tools

We can’t praise JavaScript by saying it is the best thing that happened in a developer’s life because that’s not true. Yes, JS has many cool things and great features, but it also has disadvantages that make you want to jump off a cliff.

Some developers say that the entire language is poorly designed, making it have way too many errors and inconsistencies. We’re not going to get into that fight. Whatever your posture on JavaScript, the universal truth is that you need it to develop websites; currently, 95.2% of all websites use it.

The good news is that there are many JavaScript developer tools to help you control your JS-driven suicidal tendencies and find easier solutions to improve your workflow and productivity. Let’s check them out: 

1. Visual Studio Code

If you’ve been into web development, you understand the importance of having a website with user-friendly elements. React is the perfect tool to help you achieve an interactive website.

React main features:

  • ReactJS offers stable code because it uses downward data flow only (when changes happen in the small structure, the big structure is not affected).
