# PERL join Function

## Syntax

join EXPR, LIST

## Definition and Usage

Combines the elements of LIST into a single string using the value of EXPR to separate each element. It is effectively the opposite of split. Note that EXPR is only interpolated between pairs of elements in LIST; it will not be placed either before the first or after the last element in the string. To join together strings without a separator, supply an empty string rather than undef.

## Return Value

- Joined string

## Example

Try out following example:

    #!/usr/bin/perl

    $string = join( "-", "one", "two", "three" );
    print"Joined String is $string\n";

    $string = join( "", "one", "two", "three" );
    print"Joined String is $string\n";

    It produces following result

    Joined String is one-two-three
    Joined String is onetwothree
