Get text from the textarea
Question
How do I create a function that extracts the text from the textarea and divides it into the individual words and puts all the words in an array?
<body>
<textarea name="text" id="" cols="30" rows="10" id="textarea"></textarea>
<button id="button">Click</button>
<script src="script.js"></script>
</body>

var btn = document.getElementById("button");
btn.addEventListener("click", getText);
function getText(){
}
</script>

You have 80% done :-)
Now you need to get the value from the textarea, replace the spaces with this regexp /\\s+/ (this is just to replace consecutive spaces) and then split the text by ' ' (single space)
var btn = document.getElementById("button"); btn.addEventListener("click", getText); var array; function getText() { var textarea = document.getElementById('text'); array = textarea.value.replace(/\\s+/g, ' ').split(' ').filter((e) => e.length > 0); console.log(array); }
<textarea name="text" id="text" cols="30" rows="10" id="textarea">Hello World</textarea> <button id="button">Click</button>
See? now you're getting the values into an array.
UPDATED : According to @phil the g modifier is necessary to avoid inconsistent with new lines at first position.

function getText(){
var text = document.getElementById("textarea").value;
var words = text.split(/\s+/);
return words;
}
The value gets text from textarea and Split breaks text into words using spaces.
