Programming Languages
Python, JavaScript, TypeScript, Java, C#, Go, and Rust - each language end to end, from zero to advanced.
Basic
Python From Zero Learn Python from nothing to genuinely advanced: install and the basics, then objects and tooling, then the deep half - the data model, generators, decorators, typing, concurrency and the GIL, performance, and packaging - all in small, runnable steps with clear explanations.
JavaScript From Zero Learn JavaScript from nothing to genuinely advanced: where it runs, values and types, collections, control flow, modules, async and the DOM - then the deep half: scope and closures, this and prototypes, generators, the event loop, functional JS, bundlers, performance, and the road to TypeScript. Small, runnable steps, clear explanations.
Go From Zero Learn Go from nothing to genuinely advanced: install it and the basics, then the deep half - interfaces, generics, real concurrency patterns, error handling, the runtime scheduler and GC, testing and profiling, the standard library, and performance - all mental-model-first, with clear explanations.
Rust From Zero Learn Rust from nothing to genuinely advanced: install it and the basics, then ownership - and then the deep half: lifetimes, traits and generics, smart pointers, error handling, fearless concurrency, iterators, macros, and performance and unsafe. Mental-model-first, with clear explanations.
Java From Zero Learn Java from nothing to genuinely advanced: install the JDK and the basics - types, classes, objects, collections - then the deep half: generics, lambdas and streams, modern records and pattern matching, concurrency, the JVM and its garbage collector, testing, and performance. Mental-model-first, with clear explanations.
C# From Zero Learn C# from nothing to genuinely advanced: install .NET and the basics - types, classes, objects, collections - then the deep half: generics, delegates and lambdas, LINQ, modern records and pattern matching, async/await, the .NET runtime and its garbage collector, testing, and performance. Mental-model-first, with clear explanations.
C From Zero Learn C from nothing to genuinely understanding it: install a compiler and write real programs, then the deep half - pointers, manual memory, the stack vs the heap, and undefined behavior - the things that separate writing C from understanding it.
C++ From Zero Learn C++ as its own language, not 'C with extras': the object model, RAII, value semantics, templates, the STL, and modern C++ - mental-model-first, from your first compile to why the Rule of Five exists.
Intermediate
TypeScript From Zero Learn TypeScript from nothing to genuinely advanced: install it and the basics - types, functions, interfaces, unions, generics, classes, and the build - then the deep half: the structural type system, utility and mapped types, conditional and template-literal types, and typing the real world. Mental-model-first, with clear explanations.
