Nashorn vs GraalVM

Developers should learn Nashorn when building Java applications that require dynamic scripting capabilities, such as embedding JavaScript for configuration, rules engines, or plugin systems meets developers should learn graalvm when building high-performance, polyglot applications that require low latency and reduced memory footprint, such as cloud-native microservices, serverless functions, or data processing pipelines. Here's our take.

Nashorn

Nice Pick

Developers should learn Nashorn when building Java applications that require dynamic scripting capabilities, such as embedding JavaScript for configuration, rules engines, or plugin systems

Pros

• It is particularly useful in scenarios where you need to leverage existing JavaScript libraries or allow users to write custom scripts that interact with Java objects, such as in enterprise applications, testing frameworks, or server-side scripting environments
• Related to: java, javascript

Cons

• Specific tradeoffs depend on your use case

GraalVM

Developers should learn GraalVM when building high-performance, polyglot applications that require low latency and reduced memory footprint, such as cloud-native microservices, serverless functions, or data processing pipelines

Pros

• It is particularly useful for Java applications seeking faster startup times and lower memory usage through native image compilation, and for projects that integrate multiple languages, enabling efficient cross-language calls without heavy overhead
• Related to: java, native-image

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Nashorn is a tool while GraalVM is a platform. We picked Nashorn based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Nashorn wins

Based on overall popularity. Nashorn is more widely used, but GraalVM excels in its own space.
