while 循环语句流程
    英文回答：
    While loop is a control flow statement that allows a block of code to be executed repeatedly as long as a certain condition is true. It is a fundamental construct in programming and is widely used in various programming languages.
    The basic structure of a while loop consists of a condition and a block of code. The condition is evaluated before each iteration, and if it is true, the code block is executed. After the execution of the code block, the condition is evaluated again, and the process continues until the condition becomes false.
    Here is an example in Python:
javascript是什么意思中文翻译    count = 0。
    while count < 5:
        print("Count:", count)。
        count += 1。
    In this example, the condition `count < 5` is checked before each iteration. As long as the condition is true, the code block inside the while loop is executed. The variable `count` is incremented by 1 in each iteration, and the loop continues until `count` becomes 5.
    Another example in JavaScript:
    let i = 0;
    while (i < 3) {。
        console.log("i:", i);
        i++;
    }。
    In this JavaScript example, the condition `i < 3` is checked before each iteration. The code block inside the while loop is executed as long as the condition is true. The variable `i` is incremented by 1 in each iteration, and the loop continues until `i` becomes 3.
    While loops are often used when the number of iterations is not known in advance or when the loop should continue until a certain condition is met. They provide flexibility and allow for dynamic control flow in a program.

    while循环是一种控制流语句，允许一段代码被重复执行，只要特定条件为真。它是编程中的基本构造，在各种编程语言中被广泛使用。
    while循环的基本结构由条件和代码块组成。在每次迭代之前，条件被评估，如果条件为真，则执行代码块。在代码块执行之后，条件再次被评估，这个过程会一直持续，直到条件变为假。
    以下是一个Python的例子：
    count = 0。
    while count < 5:
        print("Count:", count)。
        count += 1。
    在这个例子中，条件`count < 5`在每次迭代之前被检查。只要条件为真，while循环内部的代码块就会被执行。变量`count`在每次迭代中递增1，循环会一直进行，直到`count`变为5。
    另一个JavaScript的例子：
    let i = 0;
    while (i < 3) {。
        console.log("i:", i);
        i++;
    }。
    在这个JavaScript的例子中，条件`i < 3`在每次迭代之前被检查。只要条件为真，while循环内部的代码块就会被执行。变量`i`在每次迭代中递增1，循环会一直进行，直到`i`变为3。
    while循环经常在迭代次数未知或循环应该一直持续直到满足某个条件时使用。它们提供了灵活性，并允许在程序中进行动态的控制流程。
