Interfaces (1/5)
What are interfaces in TypeScript?
- They describe the shape of an object, including its properties and methods.
- They provide a way to implement custom types
- In TS, two types are compatible if their internal structure is compatible. This allows us to implement an interface just by having the shape the interface requires, without an explicit implements clause.
- Not all properties in an interface are required, each optional property is denoted by a ? at the end of the property name in the declaration.
