I fail to understand what is happening between these two array creation, tested on cygwin GNU bash
$ array=('hello world' how are you)
$ echo $array
'hello world' <----- This is expected
EDIT : As chepner pointed it out the output is
hello world <----- no ''
Now with variable assignment as an intermediate step
$ words="'hello world' how are you"
$ echo $words
'hello world' how are you
$ array=($words)
$ echo $array
'hello <----- Why was it split with ' '?
