What Is the JavaScript Double Question Marks (??) Operator?

This article provides a detailed tutorial on JavaScript's Nullish Coalescing Operator (??), also known as the double question marks operator. It explains the operator's purpose of returning a default value when the left-hand operand is null or undefined, contrasts it with traditional if-statements and the ternary operator, and demonstrates its use with code examples. It also covers its precedence and combination with the optional chaining operator.
