2|5 for of for of 循环是 ECMAScript6 中新添加的一个循环方式,与 for in 循环类似,也是普通 for 循环的一种变体。使用 for of 循环可以轻松的主要用来遍历数组|字符串,其语法格式如下: for (var tiem in arr) { // 要执行的代码 } 示例代码: arr = [1, 2, 3, 4] for (var item of arr)...

1 2 In the above program, theforloop is used to print the value ofiin each iteration. Here, notice the code: if(i ==3) {break; } This means, wheniis equal to3, thebreakstatement terminates the loop. Hence, the output doesn't include values greater than or equal to 3. ...
0 1 2 4 In the above example, if i == 3: continue skips the current iteration when i is equal to 3, and continues the next iteration. Hence, the output has all the values except 3. Note: We can also use the continue statement with a while loop. continue Statement with while Loo...
