For loop example: 1 2 3 4 5 6 var sum = 0; for (var i=1; i<=100; i++) { sum += i; } alert(sum); //5050 You may use break to jump out of the loop:1 2 3 4 5 6 7 var sum = 0; for (var i=1; i<=100; i++) { if (i == 50) break; stop the loop...
which means that it takes the command right after the loop, without executing the rest of it, but instead doing whatever code is next. Here’s an example of how you can use it:

Example Let's look at an example that shows how to use a for loop in JavaScript. For example: for (var counter = 1; counter < 5; counter++) { console.log(counter + ' - Inside for loop on TechOnTheNet.com'); } console.log(counter + ' - Done for loop on TechOnTheNet.com')...
JavaScript For Loop ExampleThis example will show you how to create a simple for loop that prints out the value of our counter until the counter reaches 5. Pay special close attention to the three different items that are on the first line of the for loop code. These are the important ...
In JavaScript, the for loop is used for iterating over a block of code a certain number of times, or to iterate over the elements of an array. Here's a quick example of the for loop. You can read the rest of the tutorial for more details. Example for (let i = 0; i < 3; i...
In that lesson, we saw that the While loop executes code while a condition is true.In this lesson, we will see that the JavaScript For loop executes code for a specified number of times. Therefore, we could rewrite the example from the previous lesson to use a for loop....
Example for (i = 0; i < 5; i++) { text += "The number is " + i + ""; } Try it yourself » From the example above, you can read:Statement 1 sets a variable before the loop starts (var i = 0).Statement 2 defines the condition for the loop to run (i must be less ...
