In JavaScript, both|| and&& are logical operators that return the first fully-determined“logical value” when evaluated from left to right.
和&&都是逻辑运算符,用于在从左至右计算时,返回第一个可完全确定的“逻辑值”。
And&& are logical operators that return the first fully-determined“logical value” when evaluated from left to right.

表达式是一个表达式,它具有对布尔变量进行操作的关系和/或逻辑运算符。
A boolean expressionis an expression that has relational and/or logical operators operating on boolean variables.
You can include the Not logical operator to evaluate the opposite condition(that is, whether expr lies outside the range defined by value1 and value2).
逻辑运算符&&和||是用来计算两个表达式而获得一个结果值。
Logic operators&& and|| are used when evaluating two expressions to obtain a single result.
请注意,在第三种情形下,我们使用逻辑运算符OR来一起查询第一和第二种情形。
Note that in the third case we are using the logic operator OR to query the first and second cases together.
逻辑运算符&&和||以一种特殊的方式处理不同类型的值。
The logical operators&& and|| handle values of different types in a peculiar way.
