【for变量in序列:】的功能是依次遍历序列中的元素,并在每一次循环中将一个元素赋值给变量,然后执行后续的循环体内容 执行以下程序段 解析: 进入for i循环,依次将序列【列表[1,‘n’,[5,2]]】中的元素赋值给变量i并执行循环体中的print(i) 第一次将1赋值给i,输出i为刚赋值的1,结束本次循环后进入下一次...

JavaScript 支持不同类型的循环:for - 多次循环代码块 for/in - 遍历对象的属性 for/of - 循环遍历可迭代对象的值 while - 在指定条件为真时循环代码块 do/while - 循环一次代码块,然后在指定条件为真时重复循环注释: 不要使用 for/in 语句循环遍历索引顺序很重要的数组。请改用 for 语句。

Javascript is famous for its callback-hell coding style. In Flatscript it allows developers to write code in synchronous styles and the compiler will translate it to asynchronous Javascript code. For example, Flatscript code like: for i range 10 if i != 0 setTimeout(%, 1000) console.log...
