Removing elements from an array while iterating in while loop

Question

I want to get random names from the nameArray and each time delete that element, so that in the end, I have got all names and the nameArray is empty. Nothing displays in the console.

let i;
let nameArray = ['Chara','Lisette','Corine','Kevin','Carlee'];
while(i < nameArray.length){
let name = nameArray[ Math.floor( Math.random() * nameArray.length )];
 console.log(name);
 delete nameArray[i];
 }

• Masoud Keshavarz: You made an infinite loop! This statement (i < nameArray.length) is always correct.

Answer 1

i is never initialized nor updated, so the while loop doesn't make too much sense. You can try this instead:

let nameArray = ['Chara','Lisette','Corine','Kevin','Carlee'];
while(nameArray.length > 0) { // while the array is not empty
 let i = Math.floor(Math.random() * nameArray.length); // pick a random element index
 console.log(nameArray[i]); // print the element
 nameArray.splice(i, 1); // remove the element from the array
}
