JS - go throught a text, make array entry after each "."

Question

I'm new to JavaScript. I have a text with several sentences and I want each sentence to be an entry in a array named sentences and alert("new entry was made"). So I have to loop through and whenever there is a "." a new entry would start. But How can I go through a text till its end?

var sentences = []
var myText= "I like cars. I like pandas. I like blue. I like music."

Answer 1

You can do it by splitting myText on ". " and then trimming and adding back the full stop.

jsFiddle

var myText = "I like cars. I like pandas. I like blue. I like music."
var sentences = myText.split(". ");
for (var i = 0; i < sentences.length; i++) {
    if (i != sentences.length - 1)
        sentences[i] = sentences[i].trim() + ".";
}

Splitting the text on ". " instead of on "." will mean it will work on sentences like "That costs $10.50."
