原文 2018-10-18 11:03:18 1 1 javascript/ if-statement/ ternary

任何人都可以向我解释这两个陈述之间有什么区别，以及为什么第二个陈述不起作用，第一个陈述不起作用：

if (finalWord.length > 140) return false; else return finalWord;
(finalWord.length > 140) ? false : finalWord;

It looks, you miss the return statement .

return finalWord.length > 140 ? false : finalWord;

You could shorten it to

return finalWord.length <= 140 && finalWord;
