/**
 * #### Difference
 *
 * Gets the difference of the two arrays or sets
 *
 * * * *
 * Example:
 * ```typescript
 * import { difference } from "@thalesrc/js-utils/array";
 *
 * const base = ["a", "b", "c", "d", "a", "b", "c", "d"];
 *
 * difference(base, ["a", "b"]); // ["c", "d", "c", "d"]
 * difference(base, ["a", "b"], true); // ["c", "d", "a", "b", "c", "d"]
 * ```
 *
 * Array Prototype Example:
 * ```typescript
 * import "@thalesrc/js-utils/array/proto/difference";
 *
 * const base = ["a", "b", "c", "d", "a", "b", "c", "d"];
 *
 * base.difference(["a", "b"]); // ["c", "d", "c", "d"]
 * ```
 *
 * Set Prototype Example:
 * ```typescript
 * import "@thalesrc/js-utils/set/proto/difference";
 *
 * const base = new Set(["a", "b", "c", "d"]);
 *
 * base.difference(["a", "b"]); // Set(["c", "d"])
 * ```
 * * * *
 * @param base Base Set or Array
 * @param substraction Set or Array to remove its values from the base
 * @param allDiff By default all the same items encountered in substraction will be removed, set this argument as true to get real difference
 * @returns Difference of base from substraction
