A common mistake: Types with many optional properties
A common mistake: Types with many optional properties.
Why? Because the property is often required in some cases.
So, optional properties often reduce type safety.
Solution: If properties are optional in some cases, create separate types for those cases.
#typescript
A helpful mindset: "Wait, I just marked this property as optional. Is it truly optional 100% of the time?"
If it's required in some cases, I should make a separate, well-named type.
This avoids lying to the compiler. The more the compiler knows, the better.
