There was a question on a coding interview and I felt like it would be easy by using isNaN
within a for loop and then splicing that index. Come to find out it didn't work and I haven't found a single thing online that shows how to do it. This is without jQuery and just strictly ES6 javascript. Say you are given an array..... arr = [2, "a", 4, "b", 3, 5, "c"]
. Without making a new array, modify the existing array to contain only numbers. How would you go about removing all non-numbers from the array? I have not found one solution online that does not use jQuery.
