How can I convert a comma-separated string to an array?

Question

I have a comma-separated string that I want to convert into an array, so I can loop through it.

For example, I have this string

var str = "January,February,March,April,May,June,July,August,September,October,November,December"; 

Now I want to split this by the comma, and then store it in an array.

Is there anything built-in to do this?

Of course I can write a custom function to do this. Or even better import one of the many existing libraries already written and well tested to process comma separated values, such as jquery-csv. But is there something built in?

Answer 1

var array = string.split(','); 

MDN reference, mostly helpful for the possibly unexpected behavior of the limit parameter. (Hint: "a,b,c".split(",", 2) comes out to ["a", "b"], not ["a", "b,c"].)
