How to turn a string into an array under a specific delimiter

Question

I have this string in javascript:

var st="ab,cd,ef,gh";

how can make this string as an array with a length equal to 4 example:

st should be like this : [ab cd ef gh]

Answer 1

Use split(..)

st.split(",")

Outputs:

["ab", "cd", "ef", "gh"]

Answer 2

This would give you an array of four string elements

        var st="ab,cd,ef,gh";
        string[] stArray = st.Split(',');

so for example

        stArray[1]

would return "cd"
