How to split string into 2 parts after certain position

Question

For example I have some random string:

str = \"26723462345\"

And I want to split it in 2 parts after 6-th char. How to do this correctly?

Answer 1

Here's a reusable version for you:

str       = "26723462345"
n         = str.length
boundary  = 6
head      = str.slice(0, boundary) # => "267234" 
tail      = str.slice(boundary, n) # => "62345" 

It also preserves the original string, which may come in handy later in the program.
