how to use the stubarray function from the lodash library in typescript

To use the stubArray function from the lodash library in TypeScript, you need to install the lodash library first by running the following command:

index.ts
npm install lodash

Then, you can import the stubArray function in your TypeScript code by writing:

index.ts
import { stubArray } from 'lodash';

2 lines

The stubArray function creates a new empty array, which can be useful as a placeholder or default value for functions that require an array argument.

Here is an example of using the stubArray function in a TypeScript function:

index.ts
function myFunction<T>(myArray: T[] = stubArray()): void {
  // do something with myArray
}

4 lines

In this example, the myFunction function takes an optional myArray argument of type T[] (an array of generic type T). If the myArray argument is not provided, the stubArray function creates an empty array of type T[] as a default value.

Note that you can use generics to specify the type of the elements in the array when calling the myFunction function, like this:

index.ts
myFunction<string>(['a', 'b', 'c']); // pass an array of strings
myFunction<number>([1, 2, 3]); // pass an array of numbers
myFunction<boolean>([]); // pass an empty array of booleans

Using the stubArray function can help make your TypeScript code more concise and readable by providing a consistent, empty array value that can be used as a default argument.
