为什么会这样呢？
let number = 5
const result = number == 4 ? 'true 1' : 'false 1' || number == 3 ? 'true 2' : 'false 2' || number == 5 ? 'true 3' : 'false 3'
console.log(result)//返回结果为true 2 回答true 2为什么会这样？

您的陈述
被解释为好像被写
In particular, this part
('false 1' || number ==3)istruebecause'false 1'is a non-empty string.I am not sure what you were attempting, but note that
? :ultimately can have just one value: either the value of the first expression, or the value of the second. Thus those'false n'strings really don't make any sense: either one of those conditional tests ofnumberwill be true, or none will be.
