/**
* Checks if the `subset` array is entirely contained within the `superset` array.
*
*
* @template T - The type of elements contained in the arrays.
* @param {T[]} superset - The array that may contain all elements of the subset.
* @param {T[]} subset - The array to check against the superset.
* @returns {boolean} - Returns `true` if all elements of the `subset` are present in the `superset`, otherwise returns `false`.
*
* @example
* ```typescript
* const superset = [1, 2, 3, 4, 5];
* const subset = [2, 3, 4];
* isSubset(superset, subset); // true
* ```
*
* @example
* ```typescript
* const superset = ['a', 'b', 'c'];
* const subset = ['a', 'd'];
* isSubset(superset, subset); // false
* ```
