Logical OR operator

The Logical OR operator (||) is a JavaScript operator that evaluates two operands and returns the value of the first truthy operand.

It is typically used in conditional statements or assignments to provide fallback or default values. When the left operand is truthy, the operator returns the value of the left operand without evaluating the right operand.

If the left operand is falsy (e.g., false, 0, null, undefined, NaN, or an empty string), the operator evaluates the right operand and returns its value.

This behavior makes the Logical OR operator useful for providing default values or handling optional values in JavaScript.

For example, const result = value || defaultValue; assigns value to result if value is truthy, but if value is falsy, it assigns defaultValue to result.
