Editing Logical disjunction (section)

===Logical operation===
Many languages distinguish between bitwise and logical disjunction by providing two distinct operators; in languages following [[C (programming language)|C]], [[bitwise disjunction]] is performed with the single pipe operator (<code>|</code>), and logical disjunction with the double pipe (<code>||</code>) operator.

Logical disjunction is usually [[Short-circuit evaluation|short-circuited]]; that is, if the first (left) operand evaluates to <code>true</code>, then the second (right) operand is not evaluated. The logical disjunction operator thus usually constitutes a [[sequence point]].

{{anchor|parallel-or}}In a parallel (concurrent) language, it is possible to short-circuit both sides: they are evaluated in parallel, and if one terminates with value true, the other is interrupted. This operator is thus called the ''parallel or''.

Although the type of a logical disjunction expression is Boolean in most languages (and thus can only have the value <code>true</code> or <code>false</code>), in some languages (such as [[Python programming language|Python]] and [[JavaScript]]), the logical disjunction operator returns one of its operands: the first operand if it evaluates to a true value, and the second operand otherwise.<ref>{{cite web |title=Python 3.12.1 Documentation - The Python Language Reference - 6.11 Boolean operations |url=https://docs.python.org/3/reference/expressions.html#boolean-operations |access-date=25 Dec 2023}}</ref><ref>{{cite web |title=JavaScript References - Expressions & Operators - Logical AND (&&) |date=25 September 2023 |url=https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Logical_AND |access-date=25 Dec 2023}}</ref> This allows it to fulfill the role of the [[Elvis operator]].
