While going through tutorial, I ran into below where
author is using map command to split up the array using space and
get below results
------------foo.txt---------
hi how are you
I am fine

-----------when I run with map ---
hi how are you I am fine

I also was wondering if I could do the same w/ just array
---------- when I run with array split
@lines1 is 2

Why is this evaluating split of array to scalar?
**update** ; also, when I run below I get

i am fine

open (FH, "foo.txt") ;
while (<FH>) {
  chomp;
  @lines1 = split / /, $_;
}
close FH;
print "@lines1\n";

###### map code ############
open (FH, "foo.txt");
my @words = map { split } <FH>;
close FH;
print "@words\n";
############### array split##########
open (FH, "foo.txt");
my @lines = <FH>;
close FH;
my @lines1 = split(' ', @lines);
print "\@lines1 is @lines1";
