    FAQ

    Frequently asked questions about the technology comparison

    Salary comparison by role · IT skill trends

    How is the suitability per use case determined?

    For each technology we editorially assess how well it fits typical use cases (e.g. web backend, frontend, data science). The values are meant as guidance, not absolute truth.

    Where does the market demand come from?

    The number of open jobs comes directly from the active IT job ads on Jobriver - a real, continuously updated indicator of demand in the job market.

    Can I compare languages and frameworks together?

    Yes. You can choose freely - but the comparison is most meaningful within one category, e.g. two frontend frameworks or two languages.

    What do the 1-5 ratings mean?

    Learning curve, performance and popularity are compact editorial assessments on a scale from 1 to 5. For the learning curve, a lower value means an easier start.

    Which technology is the best?

    There is no universally best language or framework - it depends on the use case, the team and the existing ecosystem. That is exactly what this comparison is for.

    How current is the data?

    Market demand updates continuously from the active job ads. We maintain the editorial assessments regularly.
