/**
|
||
|
|
* 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.
|
||
|
|
*
|
||
|
|
* @template T - The type of elements in the array.
|
||
|
|
* @param {T[]} firstArr - The first array to compare.
|
||
|
|
* @param {T[]} secondArr - The second 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.
