Aug 26 2025 The nullish coalescing ?? operatoris a logicaloperatorthat returns its right hand side operand when its left hand side operand is null or undefined and otherwise returns its left hand side operand It is most commonly written as x ?? y but varies across programming languages
While its behavior differs between implementations thenull coalescingoperatorgenerally returns the result of its left most operand if it exists and is not null and otherwise returns the right most operand Nov 1 2025 Thenull coalescingoperator?? returns the value of its left hand operand if it isn t null otherwise it evaluates the right hand operand and returns its result

As it treats null and undefined similarly well use a special term here in this article Jan 8 2025 In JavaScript the nullish coalescing ?? operatoris a logicaloperatorthat evaluates the left hand operand and returns it if it is not nullish i.e
not null or undefined TheNullish Coalescing operatorin JavaScript is represented by two question marks ??
It takes two operands and returns the first operand if it is not null or undefined The ORoperator uses the right value if left is falsy while the nullish coalescingoperator?? uses the right value if left is null or undefined
These operators are often used to provide a default value if the first one is missing The null conditionaloperator ?
