What is the use of || Operator in JavaScript ?
In JavaScript, the ||
operator is known as the logical OR operator. Its purpose is to perform a logical OR operation between two operands. It returns true
if at least one of the operands is true
, and false
otherwise.
Example: Here, true || false
evaluates to true
because at least one operand (true
) is true
. In the second example, false || false
evaluates to false
because neither operand is true
. In the third example, true || true
also evaluates to true
because both operands are true
.
Javascript
let result = true || false ; console.log(result); // Output: true result = false || false ; console.log(result); // Output: false result = true || true ; console.log(result); // Output: true |
Output
true false true
