chore: fix JavaScript lint errors (issue #13114)

[mantrapatel05]

Description

Replaced new Array(n) with array literals + .push() in benchmark.js to fix the stdlib/no-new-array errors (12 of them).

Also checked the doctest error mentioned in the issue (read-file-list/examples/index.js) but couldn't reproduce it on current develop — the output already matches the comments. Might've been fixed already, happy to look again if needed.
