I was hoping to modify the original array. Filter will leave the original
in tact and place the working articles in a new array. Kind'a sloppy for
this purpose in my view.
Array.slice is for strings which are just essentially an array of
characters. Slice returns the portion of a string between two elements
such as 0 for the first and indexOf(some letter) for the end point. Not
quite what we're looking for.
Here's an idea what I've been reading:
https://love2dev.com/blog/javascript-remove-from-array/
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/splice
https://www.freecodecamp.org/news/lets-clear-up-the-confusion-around-the-slice-splice-split-methods-in-javascript-8ba3266c29ae/
Best,
Erik

My docs say Array has 'slice', not 'splice'.
That being said, I would expect you to have better luck using
Array.filter, takes a callback function and an optional 'this'
parameter and returns an array with all elements for which the
callback return is not false.

Hi all, I just tried to remove items from an array of html elementsusing
splice() and got this error that array.splice is not a function. Anyidea
why? I've read four or five articles but nothing illuminating.didn't
My situation is that I wanted to get elements by tag name so that I
have to use a custom class. So I swept the elements into an array andthey
work just fine. Unfortunately, there were more of the same, in this caseconsole.
articles in my production environment than there are in my test
environment. I don't need the extra ones, so thought splice would be an
easy way to pull them out.
I looped through the array, testing a condition. If they meet the
condition they get pulled out. Otherwise they stay.
But the splice method is not a function or so I'm told by my error
Any suggestions very much appreciated as always.
Thanks,
Erik
