Nullish Coalescing: The Better || Operator in JavaScript!!! #javascript
Показать описание
The nullish coalescing operator (??) was introduced in ECMAScript 2020 (ES11). It allows you to provide a fallback value only when the left-hand operand is null or undefined. This contrasts with the || operator, which checks for any falsy value (such as 0, false, "", or NaN) and replaces it.
OR Example -
let value = 0;
?? Example -
let value = 0;
The operator is especially useful when you want to differentiate between "missing" values (null or undefined) and "valid" values like 0 or false, which would otherwise be incorrectly handled by ||.
