Javascript Array forEach()中无法return和break,代替方法some()与every(),我们都知道for循环里要跳出整个循环是使用break,但在数组中v==num){break;}cons
我们都知道for循环里要跳出整个循环是使用break,但在数组中用forEach循环如要退出整个循环使用break会报错,使用return也不能跳出循环。 使用break将会报错: 代码语言:javascript 复制 vararr=[1,2,3,4,5];varnum=3;arr.forEach(function(v){if(v==num){break;}console.log(v);}); ...

const sum = addArrayElements(arr, add); console.log(sum); // 15 2. 纯函数 纯函数是指没有副作用(不改变外部状态)并且输出仅由输入决定的函数。纯函数可以更容易地进行单元测试和调试,并且可以更好地支持函数式编程的概念。 // 纯函数示例:将一个数组中的所有元素转换为字符串 ...
Write a JavaScript program that returns 1 if the array is sorted in ascending order. It returns -1 if it is sorted in descending order or 0 if it is not sorted.Calculate the ordering direction for the first pair of adjacent array elements. Return 0 if the given array is empty, only...
