This section is based on the answers of the respondents who chose JavaScript or TypeScript as one of their three primary programming languages.


JavaScript is the most popular programming language in the world – 60% of developers use JavaScript!

JavaScript frameworks and libraries

I am very excited to see general popularity and interest in meta frameworks. This is the logical next step of modern web development and single-page apps.

Languages most often used together with Javascript and TypeScript

Among the languages used with JavaScript and TypeScript on the backend, Java is mentioned most often, closely followed by Python. The third most often used language for the backend is PHP for JavaScript developers, but C# for TypeScript developers. The same languages made it into the top three over the past three years.

Popularity of editors and IDEs for JavaScript and TypeScript development

What module bundlers or module loaders do you regularly use?

Webpack has been around for almost a decade and evolving to support developer needs with features, such as module federation and persistence caching. We see how most people use it to build and bundle their apps. Over the past two years, we have witnessed how modern tools such as Vite and esbuild are picking up more adoption to meet developers’ performance requirements with a minimalistic setup.

Usage of unit testing frameworks and tools for JavaScript and TypeScript development

I am shocked and scared at the same time that 32% are not writing unit tests at all. My hope is that higher-level tests are implemented, but it tells me that testing as a discipline needs to become more accessible, and we as a community need to lower the entrance barrier.

What style sheet languages and approaches do you regularly use?

What JavaScript is used for

Developer Advocate at JetBrains

These results clearly tell the story of “Always bet on JavaScript”. I have never considered JavaScript as my choice of programming language for Embedded Apps or Game development, but I am thrilled to hear that others do and excited for what’s to come!

What TypeScript is used for

Is TypeScript or JavaScript used for backend or frontend?

What package manager do you primarily use?

Compared to developers in general, a higher percentage of JavaScript developers – and an even higher share of TypeScript developers – use framework-specific plugins with their IDE or editor.
