2025 has undeniably been the year of AI agents. Coming into the year, it was nearly impossible to tune into any conversation in the tech ecosystem without hearing the agent buzzword thrown around. In an attempt to gain my own understanding of this new space, I started reading up on AI, machine learning, and agents. This led me to Mastra, an open-source framework for building AI agents. The best part was that it's built in my go-to language, TypeScript.

Zod v4 introduces a series of changes across three key areas: performance, API design, and tooling support. Benchmarks published by the maintainers show 14x faster string parsing, 7x faster array parsing, and 6.5x faster object parsing compared to Zod 3. These improvements are paired with reductions in TypeScript type instantiation, helping projects compile faster in large codebases. Another headline feature in this release is the introduction of @zod/mini, a lightweight distribution weighing just ~1.9 KB gzipped, designed for tree-shakable validation in modern frontend applications.

Having a well-integrated type system that makes sense and gives you optimization potential for memory layouts is generally a good idea.

The core value proposition of TypeScript is an excellent developer experience. As your codebase grows, [...] in many cases TypeScript has not been able to scale up to the very largest codebases.

In JavaScript, functions are considered first-class citizens, allowing them to be passed as parameters, returned from other functions, and assigned to variables.

The TypeScript team’s decision to rewrite the compiler in Go introduces performance improvements, but raises concerns about ecosystem disruption and long-term maintainability.

Zod 4 introduces deep internal optimizations that make parsing up to 3x faster and more memory-efficient, especially for complex, nested schemas.

According to their docs, Bun is "an all-in-one JavaScript runtime & toolkit designed for speed, complete with a bundler, test runner, and Node.js-compatible package manager".

TypeScript’s design enforces type safety from the start of the ETL process, reducing runtime errors from unexpected data types.

React Native apps can meet stringent performance requirements, but success depends on applying the right patterns effectively, eliminating performance bottlenecks.
