Microsoft's JavaScript superset adding static typing and modern language features.
Web developers, full-stack engineers, startups building web apps, Node.js backend teams
JVM-based language with null safety and 40% faster native compilation for Android and enterprise.
Android developers, JVM backend engineers, enterprises migrating from Java, teams needing null safety
TypeScript is a JavaScript superset for web and backend development with 78% more job postings, while Kotlin is a JVM-based language primarily for Android development with 40% faster compilation in recent releases. TypeScript dominates web ecosystems; Kotlin excels in mobile and enterprise Java environments.
Choose TypeScript if you're building web applications, APIs, or full-stack projects—it has superior job market demand, easier learning curve, and the largest package ecosystem. Choose Kotlin if you're developing Android apps or need strict type safety in JVM environments where performance and Java interoperability matter.
