Insert new values to specific place in Array

Hi,

do you have any Idea of how can I insert/add/push new values to specific place in Array?

For Example:
Array:
myArray[“value1”, “value4”, “value5”]

Data to insert:
“value2”, “value3”

So I need my array to look like this:
myArray[“value1”, “value2”, “value3”, “value4”, “value5”]

Thank you!
