空值合并运算符（??） - JavaScript | MDN
空值合并运算符（??）是一个逻辑运算符，当左侧的操作数为 null 或者 undefined 时，返回其右侧操作数，否则返回左侧操作数。空值合并运算符可以视为逻辑或运算符（||）的特例。后者在左侧操作数为任何假值时返回右侧操作数，而不仅仅是 null 或 undefined。换句话说，如果你使用 || 为另一个变量 foo 提供某些默认值，而你将某些假值视为可用值（例如 '' 或 0），则可能会遇到意外的行为。更多示例参见下方。空值合并运算符的运算符优先级是第五低的，直接低于 || 且直接高于条件（三元）运算符。将 ?? 直接与逻辑与（）和逻辑或（||）运算符组合使用是不可取的。这种情况下会抛出语法错误。相反，请提供括号以明确表示优先级：
Null coalescing operator - Wikipedia
It is most commonly written as x ?? y, but varies across programming languages While its behavior differs between implementations, the null coalescing operator generally returns the result of its left-most operand if it exists and is not null, and otherwise returns the right-most operand
?? and ??= operators - null-coalescing operators - C# reference
The null-coalescing operator ?? returns the value of its left-hand operand if it isn't null; otherwise, it evaluates the right-hand operand and returns its result The ?? operator doesn't evaluate its right-hand operand if the left-hand operand evaluates to non-null
Nullish coalescing operator - The Modern JavaScript Tutorial
The nullish coalescing operator is written as two question marks ?? As it treats null and undefined similarly, we’ll use a special term here, in this article
什么是JavaScript中的 “空凝聚 “运算符 - 极客教程
空值凝聚运算符是一个有用的工具，可以在你的代码中提供默认值和处理空值或未定义值。以下是JavaScript中空值凝聚运算符 (??)的语法- 这里， operand1 和 operand2 是两个操作数。如果操作数 (??)存在并且不是空或未定义，则返回 operand1。否则，它将返回 operand2。让我们看一个例子，我们创建一个常量并将其分配给字符串 “Hello “用null凝聚运算符将其分开，然后提供一个字符串 “Hello World”。左边的值不是空的，所以它将被分配给常量。

ES11 中 Nullish Coalescing Operator 的应用场景和使用方法
Nullish Coalescing Operator，中文翻译为“空值合并运算符”。它由两个问号（??）组成，用于判断一个变量是否为 null 或 undefined，并给出一个默认值，如果变量不为 null 或 undefined，则返回该变量；否则返回默认值。
Nullish coalescing operator (??) - JavaScript - MDN
The nullish coalescing (??) operator is a logical operator that returns its right-hand side operand when its left-hand side operand is null or undefined, and otherwise returns its left-hand side operand
When should I use ?? (nullish coalescing) vs || (logical OR)?
The OR operator || uses the right value if left is falsy, while the nullish coalescing operator ?? 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
ES2020 中 Nullish Coalescing 操作符的使用方法
本文将讲解 Nullish Coalescing 操作符的使用方法以及相关注意事项。 Nullish Coalescing 操作符 ?? 可以将一个空值（null 或 undefined）转化为一个默认值。它的语法是：如果 variable 不为 null 或 undefined，则返回 variable；否则会返回 defaultValue。让我们看下一个例子：在这个例子中，变量 foo 的值为 null，所以使用 Nullish Coalescing 操作符得到的结果是 bar。现在让我们来看一个不使用 Nullish Coalescing 操作符的例子，只使用逻辑运算符 ||。在这个例子中，变量 foo 的值为 0。
