Advanced TypeScript Deep Dive in Leuven

Day 1: TypeScript Mastery and Beyond

• Built-in utility types: Partial, Required, Pick, Omit, Record deep dive
• Custom utility types: Creating your own type helpers and transformations
• Conditional types: T extends U ? X : Y patterns and use cases
• Distributive conditional types: How unions flow through conditional types
• Template literal types: Dynamic string manipulation at the type level
• Mapped types: Transforming object types with keyof and in operators
• Key remapping: Using as clauses to modify property names
• Declaration merging: Extending modules, interfaces, and namespaces
• Exhaustiveness checking: Using never type to catch missing cases
• Type guards advanced: Custom type predicates and assertion functions
• Const assertions: as const and its impact on type inference
• Variance and covariance: Understanding type compatibility rules
• Advanced generics: Constraint patterns, conditional constraints, and inference
• Real-world patterns: API typing, form validation, and state management
• Performance optimization: Avoiding deep type recursion and compilation issues
• Framework integration: Advanced typing for React, Vue, or Node.js applications
