Type-safe JavaScript for scalable web development, interfaces, generics, and compiler options.
Master TypeScript: static typing, primitive types, union & intersection types, interfaces, type aliases, generics, utility types (Partial, Omit, Pick), type narrowing, and strict tsconfig settings.
tsc CLI, tsconfig.json strict flags, and compile-time verification.
Primitive types, any vs unknown, void vs never, fixed-length tuples, and enums.
Defining object contracts, extending interfaces, intersection types, and declaration merging.
Combining types with | (OR) and & (AND), literal types, and template literal types.
Function parameter typing, return inference, optional parameters, and function overloads.
Generic functions, classes, interfaces, generic constraints (extends), and keyof operator.
Type guards (typeof, instanceof), user-defined type predicates (is), and discriminated unions.
Partial, Required, Readonly, Record, Pick, Omit, ReturnType, and Parameters.
Access modifiers (private, protected, public), parameter properties, and Stage 3 decorators.
.d.ts type definition files, declare module, @types packages, and global augmentation.
strictNullChecks, noImplicitAny, monorepo project references, and linting rules.
Perform Turing-complete type computation with recursive conditional types, distributive conditional types, and template literal type inference.
Enforce nominal type safety using Branded Types (`__brand`), custom type predicates (`is`), and assertion signatures.
Analyze and manipulate Abstract Syntax Trees (AST), write custom ts-patch compiler plugins, and generate type-safe code.
Scale large enterprise codebases with TypeScript Project References (`composite: true`), solution tsconfigs, and incremental caching.
Master covariance, contravariance, explicit variance annotations (`in`, `out`), and build type-safe runtime schema validators.
