Key Differences between Perl's split and join Functions

When working with strings in Perl, the built-in functions split and join are commonly used for manipulating and formatting data. Here are the key differences between split and join:

Split Function:

  • split function is used to split a string into an array based on a specified delimiter.
  • It takes two arguments: the delimiter pattern and the string to be split.
  • For example, my @array = split(' ', $string); would split the string based on space delimiter.
  • Split function returns an array of substrings.

Join Function:

  • join function is used to concatenate elements of an array into a single string using a specified separator.
  • It takes two arguments: the separator and the array to be joined.
  • For example, my $string = join(', ', @array); would join the elements of the array with a comma and space separator.
  • Join function returns a single string.

In summary, split is used to break a string into parts, while join is used to combine elements into a single string in Perl programming.
