Multiple ways to print an array in Perl with an example

This tutorial explains multiple ways to print an array with examples

Easy way to print an array with formatted in Perl with examples

An easy way to print a variable in Perl using print statements.

if print contains an array variable, It prints all elements with space separation.

@numbers = (1, 2, 3,4,5,6);
print "@numbers\n";

Output:

1 2 3 4 5 6

Using Data::Dumper Data::Dumper🔗 prints the array or list in a stringified version.
First, Import using use Data::Dumper; into a code
Next, print the result of Dumper(\@arrayvariable) Here is an example

use Data::Dumper;

@numbers = (1, 2, 3,4,5,6);
print Dumper(\@numbers);

Output:

$VAR1 = [
1,
2,
3,
4,
5,
6
];

the map is another way to iterate an array or list. with each iteration, Print the iterated value using $_.

@numbers = (1, 2, 3,4,5,6);
map{ print "$\_\n" } @numbers;

Output:

using the join function This approach is used if you want a customization of printing the values

For example, print the array values with a hyphen(-) separation.

The join function takes a delimiter from an array and prints the string with a delimiter character separated in an array of values.

@numbers = ("one","two","three");
print join("-", @numbers);

Output

one-two-three

use Data::Printer It prints the numbers using the p function in the format of []

use Data::Printer;  
@numbers = ("one","two","three");
p @numbers;

Output:

[
[0] "one",
[1] "two",
[2] "three",
]

use JSON::XS function Sometimes, an array contains objects of multiple properties. To print the array into json format, use encode_json of an array as given below

use JSON::XS;
@numbers = ("one","two","three");
print encode_json \@numbers
