+Checks if the target value exists in a JSON object.
+
+- Use `Object.values()` to get all the values of the object.
+- Use `Array.prototype.includes()` to check if the target value is included in the values array.
+
+```js
+const hasValue = (obj, value) => Object.values(obj).includes(value);
+```
+
+```js
+const obj = { a: 100, b: 200 };
+hasValue(obj, 100); // true
+hasValue(obj, 999); // false

+Converts an array of values into an object with the same values as keys and values.
+
+- Use `Array.prototype.map()` to map each value to an array of key-value pairs.
+- Use `Object.fromEntries()` to convert the array of key-value pairs into an object.
+
+```js
+const toIdentityObject = arr => Object.fromEntries(arr.map(v => [v, v]));
+```
+
+```js
+toIdentityObject(['a', 'b']); // { a: 'a', b: 'b' }
+```
