I thought JavaScript was enough. I was wrong. It was my biggest technical mistake.
TypeScript stops your app from crashing in production. It is JavaScript with a type layer.
JavaScript lets you put a string in a number variable. Your app crashes. TypeScript warns you immediately. You save hours of debugging.
Use these patterns:
- Interfaces and Type Aliases: Define object shapes. Stop guessing if a field is userName or username.
- Generics: Handle different types safely. Stop using any. Keep your type information.
- Utility Types: Modify existing types.
- Partial: makes fields optional.
- Required: makes fields mandatory.
- Pick: selects specific fields.
- Omit: removes specific fields.
- Record: builds objects with specific keys and values.
Turn on strict mode. Do not use any everywhere. Do not ignore errors. Make any the exception.
Think about data shapes before you write code. This makes your design better. Your code gets cleaner. You find fewer bugs.
