What are best practices for working with translation tr///?

Best practices for using the Perl translation operator (tr///) include:

  • Use proper character classes to improve readability and maintainability.
  • Be mindful of performance; tr/// can be faster than regex for simple substitutions.
  • Document your code, especially if the translation is complex or not immediately clear.
  • Test your translations to ensure they work as intended across different inputs.

Here’s an example of using the tr/// operator:

# Perl script example my $string = "Hello, World!"; $string =~ tr/Hello/Hi/; print $string; # Output: Hi, World!
