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
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.
