The TypeScript utility types I reach for daily

TypeScript shines when you let the compiler do the work for you — and utility types are the fastest way to get there.

# Pick and Omit

Instead of redefining a type, derive it from the source. When the source changes, dependent types update automatically.

# Record for maps

Record<K, V> clearly describes an object used as a dictionary, replacing vague index signatures.

• Partial<T> for forms and updates
• ReturnType<T> to track a function
• Avoid 'any' — use 'unknown' and narrow

Good types are living documentation that never goes stale.
