Numbering sentences

Question

Today I am trying to number the sentences of a text, what is missing? :

var text = "ABC.DEF.XYZ";
for (i = 0, i < text.length, i++) {
var response = text.split(".").join(" i ");
}
alert(response);

Answer 1

var text = "ABC.DEF.XYZ";
var arr = text.split(".");
var response = "";

for (i = 0;i<arr.length;i++) {
response += i + arr[i];
}

alert(response);
