Bit harsh.
That was probably a node / npm thing, because they had no stdlib it was quite common to have many small libraries.
I consider it an absolute golden rule for coding to not write unnecessary code & don't write collections.
I still see a lot of C that ought not to have been written.
I'm a grey beard, and don't fear for my job. But not relying on AI if it's faster to write, is as silly as refusing a correct autocomplete and typing it by hand. The bytes don't come out better
Why should I retype something that in my life I have probably already written 10s of times?
Make your own standard library then and import that
And if you rely on AI to write that code now you still have no business writing code
