When to choose Java

  • Choose Java for Enterprise backends (Spring Boot), Microservices at scale, Big Data (Hadoop, Spark, Kafka).
  • Java is the better fit if you already optimize around its ecosystem and tooling.
  • Watch out for jvm memory overhead — apps start heavy.

When to choose TypeScript

  • Choose TypeScript for Large-scale frontend (React, Angular, Vue), Node.js backends at scale, Monorepos and shared libraries.
  • TypeScript pulls ahead most clearly in development speed.
  • Watch out for compiles to js — runtime is still javascript.
