This chapter is about iteration, which is the ability to run a block of statements repeatedly. We saw a kind of iteration, using recursion, in Section 5.8. We saw another kind, using a for loop, in Section 4.2. In this chapter we’ll see yet another kind, using a while statement. ...
for...in 语句循环一个指定的变量来循环一个对象所有可枚举的属性。JavaScript 会为每一个不同的属性执行指定的语句。 for (variable in object) { statements } 例子 下面的函数通过它的参数得到一个对象和这个对象的名字。然后循环这个对象的所有属性并且返回一个列出属性名和该属性值的字符串。 function dump...
But that’s not the end of the story. In this article I want to explore a different problem that code iteration might be pointing to. The nested iteration in the last example suggested the logic was in the wrong place. The existence of iteration at all in our newhasNamemethod (whether ...

Example 2 Avoid infinite loops. Make sure the condition in a loop eventually becomesfalse—otherwise, the loop will never terminate! The statements in the followingwhileloop execute forever because the condition never becomesfalse: // Infinite loops are bad! while (true) { console.log('Hello, ...
The statements inside the loop. iteration: One pass through (execution of) the body of the loop, including the evaluation of the condition. encapsulate: To divide a large complex program into components (like methods) and isolate the components from each other (for example, by using local vari...
For a set , the following two statements hold. 1. If T is a BEC, then there exists a T′⊆T such that T′ is a SEC. 2. If T is a SEC, then either T also is a BEC or . Proof 1. Let τ be an optimal strategy of Minimizer. If is a BEC, then , so the optimal strat...

Example bellows will show a code using do statement: do { Console.WriteLine("This is number " +i); i = i + 1; //you can write statements to do more works here } while (i <= 10); In above code, the condition “i = 10” is check after the statements in the loop is run....
