When to Use import type

Key Benefits

Improved Type Safety: By expressing interest in types alone, you encourage better type checking which eliminates some runtime errors. Reduced Bundle Size: Considering that compiled JavaScripts do not include genuine values obtained through modules, it is possible to cut down on bundle size significantly especially when you are working with bulky modules. Clearer Code Intent: With import type, code becomes more self-explanatory because it shows that only types matter as far as checking them is concerned....

When to Use import type

Type Annotations: When you are providing type information for variables, function arguments, return values or properties.Type Aliases: When creating type aliases that reference types from other modules.Interface Extensions: When extending interfaces defined in external modules.Generic Constraints: When specifying type constraints for generics that involve types from other modules....

Important Considerations

No Runtime Value Import: The imported types do not exist at runtime. You cannot use them to create instances of classes, call functions or access properties that have runtime behavior.Conditional Imports: import type statements cannot be used in conditional statements like if or switch....
