+/**
+ * Find the different values on complex, nested objects. Outputs the path through the object to
+ * each value that does not match from val1 and val2. Optionally can output the values that differ.
+ *
+ * For objects that differ greatly, can write to a file instead of the terminal for analysis
+ *
+ * ## Example
+ * ```ts
+ * const obj1 = {
+ *   key1: {
+ *     key2: [
+ *       { key3: 1 },
+ *       { key3: new Uint8Array([1, 2, 3]) }
+ *     ]
+ *   },
+ *   key4: new Uint32Array([1, 2, 3]),
+ *   key5: 362436
+ * };
+ *
+ * const obj2 = {
+ *   key1: {
+ *     key2: [
+ *       { key3: 1 },
+ *       { key3: new Uint8Array([1, 2, 4]) }
+ *     ]
+ *   },
+ *   key4: new Uint32Array([1, 2, 4])
+ *   key5: true
+ * };
+ *
+ * diffObjects(obj1, obj2, true);
+ *
+ *
+ * ```
+ *
+ * ## Output
+ * ```sh
+ * val.key1.key2[1].key3
+ *   - 0x010203
+ *   - 0x010204
+ * val.key4[2]
+ *   - 0x00000003
+ *   - 0x00000004
+ * val.key5
+ *   val1.key5 is not the same type as val2.key5
+ *   - 362436
+ *   - true
+ * ```
