Looping through a variable in JavaScript

Question

I'm trying to conditionally check a variable and iterate through a while loop, but I've not been able to get it. Here is the snippet.

if(bla==""){
  //Processing something
} else {
  while(bla==""){
    //iterating variable 'bla' till it becomes ""(blank)
    //Processing something
  }
}

First I check if a variable bla is blank and then do the processing. Otherwise I iterate the variable bla until it becomes blank in the while condition, and then do the same processing.

How can it be done?

Your code seems correct. What is not working with your solutiuon? — Nikolay

while(bla=="") will loop while it is an empty string, not until it becomes one. — Alexander O'Mara

if you want to loop until it becomes blank - the loop should be true until it becomes blank ... so while(bla!=="") — Jaromanda X

It goes into infinite loop if in the first run the variable bla is not blank — Domnick

IF you want to iterate variable 'bla' till it becomes ""(blank) you need to put condition as while(bla != "")

if (bla == "") {
  //Processing something
} else {
  while (bla != "") {
    //iterating variable 'bla' till it becomes ""(blank)

  }
  //Processing something
}

This may do the trick :

while(bla==""){
   //iterating variable 'bla' till it becomes ""(blank)
   //Processing something
}

if(bla === ""){
  //Processing something when bla is empty

}
