How to use Array Generics In Typescript
Arrays in TypeScript support generics, enabling the creation of arrays with elements of specific types, including interfaces. This approach offers a straightforward solution for organizing and manipulating data with predefined interface structures.
Syntax:
interface MyInterface<T> {
// Define interface properties/methods using type T
}
const myArray: MyInterface<number>[] = [];
Example: Define an interface MyInterface with a generic type T, allowing for flexible data storage. The array myArray is declared with elements adhering to MyInterface<number>, ensuring each element maintains type consistency with the specified structure.
Javascript
interface MyInterface<T> { value: T; } const myArray: MyInterface<number>[] = [ { value: 1 }, { value: 2 }, { value: 3 }, ]; console.log(myArray); |
Output
[{ value: 1 }, { value: 2 }, { value: 3 }]
How to Create Arrays of Generic Interfaces in TypeScript ?
In TypeScript, managing data structures effectively is crucial for building robust applications. Arrays of generic interfaces provide a powerful mechanism to handle varied data types while maintaining type safety and flexibility.
