Import from @varavel/vdl-plugin-sdk/utils/arrays.
function intersection<T>(firstArr, secondArr): T[];
Returns the intersection of two arrays.
This function takes two arrays and returns a new array containing the elements that are present in both arrays. It effectively filters out any elements from the first array that are not found in the second array.
Type Parameters
| Type Parameter | Description |
|---|---|
T | The type of elements in the array. |
Parameters
| Parameter | Type | Description |
|---|---|---|
firstArr | readonly T[] | The first array to compare. |

Returns
T[]
A new array containing the elements that are present in both arrays.
Example
const array1 = [1, 2, 3, 4, 5];
const array2 = [3, 4, 5, 6, 7];
const result = intersection(array1, array2);
// result will be [3, 4, 5] since these elements are in both arrays.
