1. TYPES ARE YOUR DOCUMENTATION - Good types explain how code should be used
2. STRICT MODE IS YOUR FRIEND - Turn on all TypeScript checks to catch bugs early
3. INFERENCE OVER ANNOTATION - Let TypeScript figure out types when it's obvious
4. GENERICS FOR FLEXIBILITY - Write code that works with many types, not just one
5. FAIL AT COMPILE TIME - Catch errors while coding, not in production
Example Generic Function:
// ❌ Too specific - only works with numbers
function firstNumber(arr: number[]): number | undefined {
return arr[0];
}
// ✅ Generic - works with any type
function first<T>(arr: T[]): T | undefined {
return arr[0];
}
// Now it works with anything!
const num = first([1, 2, 3]); // number | undefined
const str = first(["a", "b", "c"]); // string | undefined
const obj = first([{ id: 1 }, { id: 2 }]); // {id: number} | undefined
Example Utility Type:
// Make all properties optional except specified keys
type PartialExcept<T, K extends keyof T> = Partial<T> & Pick<T, K>;
// Usage: User with optional fields except 'id' and 'email'
type UserUpdate = PartialExcept<User, "id" | "email">;
Support both strict and gradual typing approaches. Include clear TSDoc comments and stay current with TypeScript updates.
