Array Element Exercise

I took it upon myself to use some of the skills that I have learned to add/remove items to an arrary

//Program adds numbers to an empty list then deletes them one by one

let numbers = [];

for (let i=2; i<=10; i+=2) {
  console.log(i);
  numbers.push(i);
  console.log(numbers);
  }

let newNum = numbers.length

if (newNum === 5){
  console.log(`List is full! Length: ${numbers.length}`);
   while (numbers.length >= 0 ) {
      let removedNum = numbers.shift();
      console.log(`Number being removed: ${removedNum} `);
      console.log(numbers);

      if (numbers.length === 0) {
        console.log('breaking loop');
        alert('Array is empty now');
        break
      }   
   }

}

I was have an issue with my while loop until I realized I made an infinite loop by accident . I corrected it by with this

while (numbers.length > 0 ) 

and removing the below lines since it was no longer needed

 if (numbers.length === 0) {
        console.log('breaking loop');
        alert('Array is empty now');
        break
      }   

Let me know how I did in troubleshooting my code and going a step a little more than hardcoding the code

Hey Joshua Moten , this is looking great!

You definitely found the reason behind the infinite loop, which is awesome. Often it is the SMALLEST thing, isn't it??
