If I try
"my, tags are, in here".split(" ,")
I get the following
[ 'my, tags are, in here' ]
Whereas I want
['my', 'tags', 'are', 'in', 'here']

you can use regex in order to catch any length of white space, and this would be like:
var text = "hoi how are you";
var arr = text.split(/\s+/);
console.log(arr) // will result : ["hoi", "how", "are", "you"]
console.log(arr[2]) // will result : "are"
"my, tags are, in here".split(/[ ,]+/)
the result is :
["my", "tags", "are", "in", "here"]
When I want to take into account extra characters like your commas (in my case each token may be entered with quotes), I'd do a string.replace() to change the other delimiters to blanks and then split on whitespace.
input.split(/\s*[\s,]\s*/)
… \s*
matches zero or more white space characters (not just spaces, but also tabs and newlines).
... [\s,]
matches one white space character or one comma
If you want to avoid blank elements from input like "foo,bar,,foobar"
, this will do the trick:
input.split(/(\s*,?\s*)+/)
The +
matches one or more of the preceding character or group.
Edit:
Added ?
after comma which matches zero or one comma.
Edit 2:
Turns out edit 1 was a mistake. Fixed it. Now there has to be at least one comma or one space for the expression to find a match.
The suggestion to use .split(/[ ,]+/)
is good, but with natural sentences sooner or later you'll end up getting empty elements in the array. e.g. ['foo', '', 'bar']
.
Which is fine if that's okay for your use case. But if you want to get rid of the empty elements you can do:
var str = 'whatever your text is...';
str.split(/[ ,]+/).filter(Boolean);
