Option 1 (Direct and straightforward):

* How Does the Bitwise OR Operator

Understanding the Bitwise OR Operator "|" in JavaScript

In JavaScript, the bitwise OR operator (|) performs a bitwise operation on two integers. It operates on the binary representation of the integers and returns a new integer that represents the result of the operation.

However, when operating on a non-integer value, such as 0.5 in our example, it is truncated to the nearest integer. This is why 0.5 | 0 returns 0.

Example:

Let's break down the example provided:

console.log(0.5 | 0); // 0
console.log(-1 | 0); // -1
console.log(1 | 0); // 1
Copy after login
  • 0.5 | 0: 0.5 is truncated to 0, and 0 | 0 = 0.
  • -1 | 0: -1 is already an integer, so -1 | 0 = -1.
  • 1 | 0: 1 is already an integer, so 1 | 0 = 1.

Summary:

In JavaScript, the bitwise OR operator "|" performs a bitwise operation on integers. If a non-integer value is involved, it is first truncated to the nearest integer before the operation is performed. This behavior ensures that bitwise operations only make sense on whole numbers.
