We can terminate awhileloop using thebreakstatement. For example, // Program to find the sum of positive numbers// the while loop runs infinitely// loop terminates only when user enters a negative numberletsum =0;// infinite loopwhile(true) {// get number inputletnum =Number(prompt("Ente...
Without the break statement, this loop would run forever. The break condition checks if count exceeds 3. $ node main.js 0 1 2 3 Break in nested loopsWhen used in nested loops, break only exits the innermost loop. main.js for (let i = 0; i < 3; i++) { for (let j = 0; j...

在forEach中,不能使用 continue 和 break ,可以使用 return 或 return false 跳出循环,效果与 for 中 continue 一样,但是该方法无法一次结束所有循环...如果直接使用 continue 或者 break 还会报错,如下所示:[1,2,3].forEach(()=>{ break;})// SyntaxError: Illegal break statement...} finally { }/...
statement 1. 2. 说明 label语句可以在代码中添加标签,以便将来使用。定义的标签可以在将来由break或continue语句引用。加标签的语句一般都要与for语句等循环语句配合使用。 // 示例 let count = 0; loop1: for (let i = 0; i < 10; ++i) {
for(leti =0; i <10; i++) { if(i ===3) {break; } text +="The number is "+ i +""; } Try it Yourself » In the example above, thebreakstatement ends the loop ("breaks" the loop) when the loop counter (i) is 3. The Continue...
