Array
Yes. Array. I know you are all thinking... "but i know this."
Well... you also said const a = []
hurts. sorry.
if const a = [] isn't an array, what is it?
Well by the end of this section we can empirically tell what it is.
Lets first just play with arrays.
First a moment on the whiteboard. Then to the node!
So lets talk about arrays. (white board time)
Covering: Lets practice our BigO!!!
- What are arrays
- Getting at specific index
- Insertion at specific index
- Deletion at specific index
Arrays
They are fixed size, continiguous memory chunks
- That means you cannot grow it
- There is no "insertAt" or push or pop. Doesn't mean you can't write those though
Questions?
Any questions at this moment? We have pretty much covered what an array is.
