How to iterate over an array and remove elements in JavaScript [duplicate]

Answer 1

Using Array.shift():

var array = [1, 2, 3, 'a', 'b', 'c'];
while (array.length > 0) {
  console.log(array.shift());
}

Edit: Probably does not suit the specs. I misread the question (only remove certain elements) and was too eager instead to add a method that was not mentioned yet...
