If I want to create a vector with 15 names, where each one is pushed into the vector individually, this code just replaces the former iteration with the new iteration instead of appending to it. Right?

`push!(arr, new_element)` appends the value to the array.

```julia
a = String[]
push!(a, "Bob")
#["Bob"]
push!(a, "Joe")
#["Bob", "Joe"]

```
