 In JavaScript, there are the **| (bitwise OR)** and **& (bitwise AND)** operators, which are different from **||** and **&&**. These operators perform bitwise operations, which means **they operate on the binary representations of numbers**. In JavaScript, there are the **| (bitwise OR)** and **& (bitwise AND)** operators, which are different from **||** and **&&**.

 Introduced in ECMAScript 2020, the optional chaining operator **?.** allows you to access properties of objects without having to check if the object or property exists. If the object or property doesn't exist, the expression **short-circuits** and returns undefined. \\  Introduced in ECMAScript 2020, the optional chaining operator **?.** allows you to access properties of objects without having to check if the object or property exists.
