In JavaScript, the do while loop allows you to run code before the loop begins to run. This style of loop is practical when you only want the loop to continue if an initial block of code yields a particular result. For example, you can use a do while loop to grab paginated data from...
log(counter + ' - Done do-while loop on TechOnTheNet.com'); In this do-while loop example, the loop would terminate once the counter exceeded 5 as specified by: while (counter <= 5) The do-while loop will continue while counter <= 5. And once counter is > 5, the loop will ...
Example:The following web document calculates the sum of even numbers between 0 to 10. The do while loop starts with x = 0 and runs until it equals to 10. If the remainder of x/2 is equals to 0 we add x with y and after completion of the loop, y returns the sum of even ...
Basic do...while loopThe following example demonstrates the basic usage of the do keyword in a do...while loop. main.js let i = 0; do { console.log(i); i++; } while (i < 5); This loop will execute the code block first, then check if i is less than 5. It continues ...

More on JavaScript while and do...while Loops What is an infinite while loop in JavaScript? An infinite while loop is a condition where the loop runs infinitely, as its condition is always true. For example, let i = 1; // always true condition while(i < 5) { console.log(i); ...
do...while 循环 do...while 循环是 while 循环的变种。该循环程序在初次运行时会首先执行一遍其中的代码,然后当指定的条件为 true 时,它会继续这个循环。所以可以这么说,do...while 循环为执行至少一遍其中的代码,即使条件为 false,因为其中的代码执行后才会进行条件验证。 语法: do { 需执行的代码 } while...
JS:设置超时时,do-while循环在函数上无限循环 我需要一个提示窗口,让用户输入一个数字。当设置一次函数(下面的代码)时,一切都可以,但这个提示窗口应该累积,直到一个整数(从200开始)的变量达到0,所以我认为do-while循环就可以了。但是,当设置do while循环时,输入数字后会立即显示提示窗口,并且不会更改任何内容。我...

do {} while (initialize counter < condition); The following example shows the palindrome of a given number. A palindrome number is a number that remains the same when its digits are reversed. In this example, I have a dowhile class and define a dowhile loop. Let's see how I implement ...
