LOGICAL OR OPERAND

 In JavaScript, the logical OR operator (||) evaluates expressions from left to right and returns the value of the first truthy operand or the value of the last operand if all operands are falsy.

In the expression 5 || true || '123', all three operands are truthy values. The number 5 is considered truthy, the boolean value true is truthy, and the non-empty string '123' is also truthy.

Therefore, when evaluating this expression, JavaScript will return the first truthy operand, which is 5.

So the result of the expression 5 || true || '123' is 5.

The logical OR operator returns the first truthy value it encounters because it short-circuits the evaluation. Once a truthy value is found, the expression no longer needs to evaluate the remaining operands because the logical OR condition is already satisfied.

which one is true, -> first left one true

false || true || false -> true

if it is true -> first left

if it is false -> first right

if it is false , it will returnt the next of false, encountered first false, nxt of false

if all are true -> left most

if all are false -> right most

false || true || false -> true

0 || null || undefined -> undefined

 5 || '123' || false -> 5 left most

null || 'Hello' || 10 -> hello

undefined || 0 || 'OpenAI' || 'GPT-3'-> next false-> open ai

if it is false , it will returnt the next of false

Certainly! Here are a few more examples of logical OR (||) expressions in JavaScript:

Example 1:

arduino
false || true || false

In this case, the second operand is true, which is a truthy value. Therefore, the expression will return true, as the first truthy operand encountered is true.

Example 2:

javascript
0 || null || undefined

All three operands in this expression are falsy values. The expression will return the last falsy operand, which is undefined.

Example 3:

bash
'' || false || 42

The first operand is an empty string (''), which is a falsy value. Since a falsy value is encountered as the first operand, the expression will return the next operand, which is false.

Example 4:

csharp
null || 'Hello' || 10

In this case, the first operand is null, which is a falsy value. However, the second operand, the string 'Hello', is a truthy value. The expression will return 'Hello', as it is the first truthy operand encountered.

Example 5:

javascript
undefined || 0 || 'OpenAI' || 'GPT-3'

The first two operands, undefined and 0, are falsy values. The third operand, the string 'OpenAI', is a truthy value. The expression will return 'OpenAI', as it is the first truthy operand encountered.

In each of these examples, the logical OR operator (||) behaves in a similar way, evaluating operands from left to right and returning the first truthy operand or the value of the last operand if all operands are falsy.
