While Loops

Please follow the instructions below.

1. Create an HTML file named while_loop_js.html within the ~/vagrant-lamp/sites/codeup.dev/public folder on your Mac.
2. An ice cream seller can't go home until she sells all of her cones. Write a JS program that generates a random number between 50 and 100 representing the amount of cones to sell. Your code should generate numbers between 1 and 5, simulating the amount of cones being bought by her clients. Use a do-while loop to log to the console the amount of cones sold to each person. This is how you get the random numbers.

// This is how you get a random number between 50 and 100
var allCones = Math.floor(Math.random() * 50) + 50;
// This is how you get a random number between 1 and 5
var cones = Math.floor(Math.random() * 5) + 1;

The output should be similar to the following:

5 cones sold...  // if there are enough cones
Cannot sell you 6 cones I only have 3...  // If there are not enough cones
Yay! I sold them all! // If there are no more cones
  ```
solution :

  ```js
  	
  var allCones = Math.floor(Math.random() * 50) + 50;
  var cones;
  var remaining = allCones;
  var msg;
  
  do{
  
  	cones = Math.floor(Math.random() * 5) + 1;
  	remaining -= cones; 
  	msg = cones + ' cones sold...';
  	if (remaining<0) {
  		msg = 'Cannot sell you ' + cones + ' cones I only have ' + (remaining + cones) +' ...';
  	};
  	if (remaining==0) {
  		msg = 'Yay! I sold them all!';
  	};
  
  	console.log(msg);
  
  }while(remaining>0);
  		
  ```



1. Use inline JavaScript to create a `while` loop that uses `console.log()` to create the output shown below.

  ```
          2
          4
          8
          16
          32
          64
          128
          256
          512
          1024
          2048
          4096
          8192
          16384
          32768
          65536
          
  ```
  solution:
  
  ```js
  var num = 2;
  while(num < 65536){
  	console.log(num+=num);
  };
  ```

1. Finally, save your work, commit the changes to your git repository, and push to GitHub.
