Methodology for Selection of Programming Languages to Learn

Our selection of the top programming languages for 2025 is based on a comprehensive evaluation framework centered around three key criteria for modern development.

The first criterion is API development capabilities, where we assessed each language's framework ecosystem and tooling support. We examined the availability and maturity of API-focused frameworks, along with their ability to handle modern API protocols and patterns. According to IEEE Spectrum's 2023 rankings, languages with robust API development capabilities consistently rank higher in developer adoption.

Modern web development compatibility serves as our second criterion. We evaluated each language's alignment with current web technologies, focusing on:

• Integration with contemporary frontend frameworks
• Support for microservices architecture
• Performance optimization capabilities
• Security features and best practices

The third criterion, integration with headless CMS systems, specifically examines how well each language works within Strapi's architecture. Understanding what is a headless CMS and the differences between traditional vs headless CMS is crucial when evaluating language integration capabilities. We analyzed:

• Native support for content delivery
• Plugin development capabilities
• Extension and customization options
• Database interaction efficiency

Our evaluation process incorporated quantitative metrics from multiple sources, including community engagement statistics, enterprise adoption rates, and developer surveys. We assigned weighted scores to each criterion based on its relevance to Strapi's ecosystem, with API development and CMS integration carrying higher weights due to their direct impact on development efficiency.

To ensure real-world applicability, we also considered factors such as learning curve, community support, and available resources. This approach helps identify languages that not only excel technically but also provide practical value for developers working with modern headless CMS platforms.
