JavaScript do until

You have to use JavaScript do…while statements to do a task until the match condition is true. Basically, you can make an infinite loop with this pattern and add a break condition anywhere in the loop with the statement break:

while (true) {
    // ...
    if (breakCondition) {            
        break;
    } 
}

The do...while is used when you want to run a code block at least one time.

JavaScript do until

Simple example code.

<!DOCTYPE html>
<html>
<body>
  <script>

   var i=0;
   while (i < 2) {
    console.log(i);
    i++;
  }

    //Alternatively, You could  break out of a loop like so:
    var i = 0;
    while(true){
      i++;
      console.log(i);
      if(i===3){
        console.log("Break");
        break;
      }
    }

  </script>
</body>
</html>
