The Programming Languages Podcast with Fexingo: Python, Rust, JavaScript, and Modern Coding

TypeScript has long been the dominant language for frontend development, but as of mid-2026, it's rapidly becoming the default choice for backend services as well. In this episode, Lucas and Luna break down why TypeScript's type system, tooling, and ecosystem are driving enterprise adoption—from NestJS and Prisma to the new Deno runtime. They discuss a specific case: how a major fintech firm migrated its Java backend to TypeScript and cut development time by 40%. Plus, a look at the numbers: 50 million weekly npm downloads and a 70% year-over-year increase in backend TypeScript projects. If you're evaluating technology stacks, this episode will give you concrete reasons why TypeScript is no longer just a frontend tool.

Lucas and Luna explore how Lua, a small and fast scripting language, has become the backbone of game development in 2026. They break down why game engines like Roblox, World of Warcraft, and even AAA titles rely on Lua for modding, rapid iteration, and runtime flexibility. Lucas walks through Lua's design philosophy—minimalist, embeddable, and blazingly fast—while Luna questions whether its lack of built-in concurrency and tooling holds it back. They compare Lua to alternatives like Python and JavaScript, and discuss its surprising resurgence in embedded systems and AI tooling. If you've ever wondered why your favorite game lets you mod so easily, this episode explains the language behind it.

Haskell has long been viewed as an academic curiosity, but in 2026 it's quietly powering production systems at places like GitHub, Meta, and a handful of fintech startups. Lucas and Luna explore how the language's strict type system and lazy evaluation are solving real-world problems around correctness and concurrency. They walk through a specific example: how a small trading firm used Haskell to eliminate an entire class of runtime errors in their order-matching engine. The hosts also discuss the trade-offs—steep learning curve, smaller ecosystem, hiring challenges—and why a growing number of teams are deciding the upfront cost is worth it. Plus, why a new generation of tooling (like the HLS language server and the GHC 9.8 release) is lowering the barrier to entry. This episode is for any developer who has wondered if pure functional programming is just a thought experiment or something you can actually ship to production.

In 2026, the Java Virtual Machine powers more than just enterprise monoliths. This episode explains how GraalVM native compilation, Project Loom virtual threads, and the rise of Kotlin and Scala on the JVM have made it a surprising contender for cloud-native and microservices workloads. Lucas and Luna drill into specific numbers: how a typical Spring Boot app starts in under 200 milliseconds with GraalVM, how Loom cuts thread overhead by 95 percent, and why companies like Netflix and Uber still run critical services on the JVM. They also discuss the ecosystem's staying power — over nine million Java developers worldwide — and why modern JVM languages are attracting Rust and Go developers looking for mature libraries without sacrificing performance. If you think the JVM is legacy, this episode might change your mind.

Lucas and Luna dive into Erlang, the 40-year-old language built for telecom-grade concurrency and fault tolerance. They explore its actor model, how it achieves 'nine nines' reliability, and why it still powers critical infrastructure from WhatsApp to Ericsson. With specific case studies on WhatsApp's 2 million concurrent connections per server and Ericsson's AXD 301 switch achieving 99.9999999% uptime, this episode unpacks why Erlang's approach to distributed systems is more relevant than ever in 2026's world of microservices and edge computing. The hosts also discuss practical trade-offs like performance and syntax, and whether newer languages like Elixir and Go owe Erlang a debt. A must-listen for developers curious about the roots of modern concurrency.

In this episode, Lucas and Luna dive into Zig, a new systems programming language that's gaining momentum in 2026. They explore why Zig's compile-time execution and manual memory management without hidden control flow are attracting developers frustrated with C's legacy baggage. Lucas breaks down how Zig handles cross-compilation out of the box, a major pain point in C development. They also discuss real-world adoption at companies like Uber and in the Bun JavaScript runtime. The hosts compare Zig's approach to Rust's ownership model, highlighting tradeoffs for different use cases. Listeners learn why Zig's simplicity and interoperability with C make it a compelling choice for embedded systems, game development, and low-level infrastructure. The episode concludes with a reflection on whether Zig could become the default for new systems projects.

Lucas and Luna explore the concept of 'vibe coding' — a new approach where beginners describe what they want in plain English and let AI generate the code. They discuss how tools like GitHub Copilot, Cursor, and Replit are reshaping the learning curve, with examples from a recent study showing 40% faster prototype completion. They debate whether this makes programming more accessible or risks creating a generation who can prompt but not debug. Specific numbers: a 2025 Stanford study found vibe coders build full-stack apps 2.5x faster but fix bugs 30% slower. The episode also touches on how this affects hiring and the role of traditional CS education.

Lucas and Luna break down why WebAssembly, originally designed for browser speed, is now becoming the runtime of choice for server-side computing. They explore how startups like Fermyon and existing cloud providers are using Wasm to achieve near-native performance with sandboxed security, and why this matters for microservices and edge computing. Specific examples include Fastly's 40% latency reduction and the rise of the component model for language interoperability.

In this episode, Lucas and Luna explore why Kotlin has become the dominant language for Android development in 2026, overtaking Java. They dive into Google's 2024 decision to make Kotlin the default for Android APIs, discuss how Jetpack Compose has reduced boilerplate by 40%, and examine case studies from companies like Uber and Airbnb that saw 30% fewer crashes after migrating. They also touch on Kotlin Multiplatform, which now powers 15% of new cross-platform apps. Listeners will learn why Kotlin's null safety, coroutines, and interoperability with Java make it a no-brainer for modern mobile development.

In episode 122 of The Programming Languages Podcast, Lucas and Luna explore Raku—the language formerly known as Perl 6—and its unique approach to concurrency. They dive into how Raku's built-in concurrency model, with features like promises, supplies, and channels, makes writing parallel code more accessible for everyday developers. The conversation contrasts Raku's design with traditional threading models in Python and Java, and examines real-world use cases from a small data pipeline project. The hosts discuss why Raku hasn't gained mainstream traction despite its innovations, and whether its ideas are influencing other languages. A concrete example of parsing log files concurrently illustrates Raku's strengths and trade-offs. The episode aims to give listeners a practical understanding of Raku's concurrency primitives and their potential impact on programming beyond niche communities.
