![]() Here is an example of Do While loop in JavaScript. This is the basic difference between do while loop and while loop. So even if the expression is FALSE then also once the statements inside the loop will be executed. Here the condition is checked at the end of the loop. } do While Loop Do While loop is little different than while loop. We can use break statement inside a while loop to come out of the loop. The above code will print 0 to 5 with a line break after each number. Let us try with this example which prints Note that here the expression is checked or evaluated before starting of the loop so if the condition returned is FALSE then the loop will never be executed. Here is the basic syntax for while loop in JavaScript. You can also see PHP while loop, ASP will loop which have more or less similar purpose and to some extent similar syntax. The default value is 1, only the immediate enclosing structure is broken out of. break accepts an optional numeric argument which tells it how many nested enclosing structures are to be broken out of. A dialog is displayed underneath the line of code. break ends execution of the current for, foreach, while, do-while or switch structure. To the left of the line of code is the line number column. ![]() This means as long as the expression is turn go for the loop. Open the file that contains the line of code you want to break on. ![]() In this example, when i was equal to 5, the break statement caused the loop to end and no further iterations were made. When the break statement is encountered, it will immediately terminate the loop and continue executing any code after the loop. Set a function to run on a timer var timer setInterval (FUNCTION, 1000). ![]() Manually throw new Error ('ERROR') in a function. ![]() For easy understanding we can say While True Loop. The break statement can be used to exit a loop in JavaScript. Client-side Javascript does not have a native abort function, but there are various alternatives to abort Javascript execution: In a function, simply return false or undefined. So the changes required in condition has to be inside the statement, otherwise the loop may go for infinite looping. While loops are conditional loops where a condition is checked at the starting of the loop and if the condition is true then the statements inside the loop is executed. ![]()
