Split String By Multiple Spaces NodeJS

Question

I have this in node:

>out
'java    1303 root  187u   CHR  166,0      0t0 14586 /dev/ttyACM0\n'
>typeof out
'string'
> out.split("\\s+"); 
[ 'java    1303 root  187u   CHR  166,0      0t0 14586 /dev/ttyACM0\n' ]

I would expect the splitted string, e.g. ['java','1303','root'...]

Answer 1

Thank you for comments. It seems that quotes are not needed at all:

> out.split(/\s+/); 

Answer 2

You split with a literal string \s+, it would split "a\\s+b" into a and b.

Use a regex, RegExp("\\s+") or /\s+/ (better, since the pattern is static):

var s = 'java    1303 root  187u   CHR  166,0      0t0 14586 /dev/ttyACM0\n';
console.log(s.trim().split(/\s+/));

I also suggest trimming the input to get rid of empty elements at the start/end.

Also note that .split(/\s+/g) = .split(/\s+/) (the global modifier is implied with String#split()).
