Opposite of Push(); (splice explanation)

Question

Say I have a array

var arrayName = [];

with three items

arrayName = ['hi', 'hey', 'hello'];

how do I delete the item 'hey' from the array?

Java and javascript are two different languages. – Sotirios Delimanolis Sep 10 '14 at 01:37 — Sotirios Delimanolis, Sep 10 '14 at 01:37
arrayName.splice(1,1); // remove from pos#1, 1 element – dandavis Sep 10 '14 at 01:38 — dandavis, Sep 10 '14 at 01:38

var hey = arrayName.splice(1,1);

EDIT: If you would prefer to get the index of a particular value, you can use:

arrayName.indexOf("hey");

deleting just changes the value, it doesn't remove the array item or affect the .length unless you do the last one... – dandavis Sep 10 '14 at 01:44
@dandavis - Derp! You're right. I keep assuming the delete keyword affects objects and arrays the same way. Edited. – maiorano84 Sep 10 '14 at 01:50
