.splice() array with array of non-sequential indexes - javascript
I have an array like this
Array['one','two','three','four','five']
and I have an array like this
Array['2','4','0']
indicating the indexes of the elements in the first array I wish to remove or .splice()
so the resulting array would look like this
Array['two','four'] // <--- note no undefined positions
If you try and loop through the indexes and just do a splice for each one, after the first splice your indexes change according to the element that was removed.
How can I accomplish t开发者_StackOverflowhis?
You can start splicing the indexes from the array in reverse order. i.e. Loop from the length of array to 0.
First splice index 4 and then index 2.
EDIT: As you mentioned the indexes array need not be in same order, you can sort the indexes array in ascending order and then implement the above logic.
