Check if the given node is a true logical expression or not.
|

|
|
|
||
|
|
The three binary expressions logical-or (`||`), logical-and (`&&`), and coalesce (`??`) are known as `ShortCircuitExpression`, but ESTree represents these by the `LogicalExpression` node type. This function rejects coalesce expressions of `LogicalExpression` node type.

@param {Node} node - The node to check.
|
||
|
|
@returns {boolean} `true` if the node is `&&` or `||`.
