Question

I want to implement a vector in Javascript with the following requirements:

• Can access an item using a numeric index (position)
• Can delete an item using a numeric index (position) – even in the middle of the collection
• Can add an item to the end of the vector

What is the preferable way to do it?

Answer 1

Arrays do this already:

var a = [1,2,3]
a[1]// Access at a particular index
a.splice(1, 1)// Delete one element at index 1
a.push(1)// Add 1 to the end
