一句话概括:for in是遍历(object)键名,for of是遍历(array)键值——for of 循环用来获取一对键值对中的值,而 for in 获取的是 键名。 for in 循环出的是key(并且key的类型是string),for of 循环出的是value。 for of 是es6引新引入的特性,修复了es5引入的for in 的不足。 for of 不能循环普通的对象...

js中forEach跳出循环问题 关于“js中forEach跳出循环问题” 的推荐: 除非输入两次,Python,否则无法跳出while循环 while True:循环永远运行,直到您显式强制循环结束。这可以通过break语句完成 For example. def spell_count(): for key, value in dnd_attributes.CharSpells.items(): print(key, sep='\n') new...
It enables some transformations that might break code logic in certain contrived cases, but should be fine for most code. You might want to try it on your own code, it should reduce the minified size. Here's what happens when this flag is on: new Array(1, 2, 3) or Array(1, 2, ...
