Learn about the differences between numeric and string comparison in Perl. Explore alternatives to traditional comparison operators like == and eq, and understand their implications and best use cases when handling different data types.

# Numeric Comparison
$value1 = 10;
$value2 = "10";
if ($value1 == $value2) {
print "Numeric comparison: Equal\n"; # This will be true
}
# String Comparison
$value1 = "10";
$value2 = "10";
if ($value1 eq $value2) {
print "String comparison: Equal\n"; # This will also be true
}
# Using alternative approach with Scalar::Util
use Scalar::Util qw(looks_like_number);
if (looks_like_number($value1) && looks_like_number($value2)) {
print "Both are numbers\n";
} else {
print "At least one is not a number\n";
}
