[Dynapi-Dev] deleteFromArray

[Pascal B. <pa...@dy...>]

Why do we still use deleteFromArray ?

can't we just use the delete array[element] syntax as used a few releases
ago by Scott?

wouldn't  delete ..   be faster then cycling thru all array elements?

deleteFromArray is still useful for removing items from ordinal
(non-associative) arrays while maintaining the correct array length.

It's not the array length that's important.. it's maintaining proper order..

It wouldn't be "prudent" if we just removed item 4 from an array of 10.
there would be a gaping hole.

hmm, so a delete array[element]  will leave a gap instead of removing the
element and move all "higher" elements down one step ?

[Jared N. <ja...@aa...>]

<script>
t=new Array(1,2,10,22,55)
delete t[1]
alert(t.length) //still 5
alert(t[1])  // undefined
</script>

yeah thats the problem with just using delete

Yes, Brandon is correct in this.  That's one of the reasons why
removeFromArray was created in the first place.  It keeps ordinal arrays
in the correct order when you remove an element.

I, in practice, when needing a name/value pair array... use objects.
It's not good practice to use a for-in on an ordinal array.. and very poor
practice to mix ordinal and associative arrays.. even though the language
supports it. Just because a language supports something doesn't mean that
it's a good thing to use.

Visual Basic is one big example of  "Just because a language supports
something doesn't mean that
 it's a good thing to use."..
