The fat comma (=>) in Perl is used to associate keys with values in a hash. It is an alternative to the regular comma and serves as a visual cue that enhances readability, especially when working with key-value pairs. Additionally, the fat comma automatically quotes strings, which reduces the need for quotation marks and simplifies code.
Here’s an example of how to use the fat comma in a Perl hash:
my %hash = (
'name' => 'John',
'age' => 30,
'city' => 'New York',
);
