Levels of TypeScript Dev
Consider TypeScript developers as falling into three levels.
These levels represent different ways developers use TypeScript, from basic typing to creating custom utility types.
insights INSIGHT
Partial Utility Type
The Partial utility type makes a type optional.
This is useful for functions like updateFood, where not all fields need updating.
insights INSIGHT
ReadOnly Utility Type
The ReadOnly utility type prevents modification of properties.
This helps define properties that shouldn't be changed after creation.
