Converting a Java ArrayList of strings to a JavaScript array

Withoug a library:

Java:

public static String toJavascriptArray(String[] arr){
    StringBuffer sb = new StringBuffer();
    sb.append("[");
    for(int i=0; i<arr.length; i++){
        sb.append("\"").append(arr[i]).append("\"");
        if(i+1 < arr.length){
            sb.append(",");
        }
    }
    sb.append("]");
    return sb.toString();
}

JSP:

var myArray = <%= toJavascriptArray(arrayList) %>;
