Lock tuple literals: as const + tuple = immutable. #TypeScriptTips #WebDev #CodingHacks
🚀 TypeScript's Smarter Types! *Inference improvements* in TS 5.x reduce boilerplate, leading to cleaner, more robust code through automatic type understanding. Are your types writing themselves yet? #TypeScriptTips #DevProductivity devblogs.microsoft.com/typescript
Dynamic strings = template literal + union types. #TypeScriptTips #WebDev #Programming
Remove unwanted types: Exclude<T,U>. #TypeScriptTips #WebDev #Programming
ReturnType<T> = extract function return type. #TypeScriptTips #WebDev #CodingHacks
Combine unknown + typeof = safest runtime type check. #TypeScriptTips #WebDev #CodingHacks
Dynamic type-safe keys with keyof + generics. #TypeScriptTips #WebDev #TS
Mapped types = transform types programmatically. #TypeScriptTips #WebDev #CodingTips
Union types + type guards = runtime safety. #TypeScriptTips #WebDev #Programming
Optional chaining: obj?.prop = no more runtime crashes. #TypeScriptTips #CodingHacks #TS
Shortcut object typing: Record<K,V> = less code, more safety. #TypeScriptTips #TS #Programming
¿Cómo podrías usar conditional types y mapped types en TypeScript para crear un tipo que, a partir de un tipo string | number, devuelva string si number nunca aparece como prop del objeto asociado? 🤔 #TypeScript #Generics #TypescriptTips
Interface : defines shape: properties & methods without implementation. Great for contracts & API design. Type : can do interfaces + unions + primitives—super flexible! Use it for complex types or aliases. #TypeScriptTips #DevTalk #JavaScript
#Typescript keyof typeof = type-safe dynamic object keys. #TypeScriptTips #WebDev #programmingjobs
Pro TS Tip ⚡: Use as const to keep object types precise: const roles = ["admin", "user"] as const; type Role = typeof roles[number]; 👉 No more unsafe strings! #TypeScriptTips
TypeScript generics permiten escribir código reusable y tipado para múltiples tipos de datos sin duplicación. Evitan casting innecesario y mejoran la seguridad del tipo en tiempo de compilación. #TypeScript #Generics #TypescriptTips 🚀 (Seed: 8562)
🔍 Real-world uses of interfaces: Type React props & API responses Build utility contracts (like loggers, services) Model array-based data like to-dos or products Less guessing. More confidence. #TypeScriptTips
3/ TS classes are verbose if you annotate every property outside the constructor. That’s where parameter properties come in: Just add public, private, or readonly to constructor parameters — TS auto-declares & assigns them! 🧼 #CleanCode #TypeScriptTips
