Question

Say for example I have an array :

[ "car", "fish", "javascript", "Star Wars" ]

And I want to select the first three in this array, but not "Star Wars".

Can I do that by using brackets somehow? Like in Rails I could this by :

array[0..2]

Is there something similar in javascript?

Answer 1

slice() and splice() are your friends:-D

Edit: For your example

var newAr = [ "car", "fish", "javascript", "Star Wars" ].slice(0, 3);
