Core Mindsets for TypeScript Developers

1. The Compiler is Your Friend

Treat the compiler as a diligent assistant that helps you catch errors early. Learning to read and understand its error messages is a crucial skill.

2. Types are Documentation

Typing is not just for the machine. It's how you document intent and data structures, helping teammates and your future self understand the code faster.

3. Start Gradually, Not Perfectly

You don't have to type everything perfectly from the start. Begin with basic types and progressively increase strictness as you get comfortable.

4. Think in Shapes

TypeScript is structurally typed. Focus on the "shape" of the data (the properties it has) rather than just which class it belongs to.
