intersectionArray<T>(a: T[], b: T[]): T[]
Returns the intersection of two arrays.
Type Parameters
- T
Parameters
- a: T[]
  The first array.
- b: T[]
  The second array.

An array containing the elements that are present in both arrays.
Remarks
This function is useful for finding common elements between two arrays. It uses a Set for efficient lookups, ensuring that the operation is performed in linear time relative to the size of the input arrays.
Example: Imports
```
// ES Module
import { intersectionArray } from '@bnidev/js-utils'

// CommonJS
const { intersectionArray } = require('@bnidev/js-utils')
```
Example: Usage
```
// Find common elements between two arrays
const array1 = [1, 2, 3, 4, 5]
const array2 = [3, 4, 5, 6, 7]
const intersection = intersectionArray(array1, array2)
// intersection will be [3, 4, 5]
```
