Problem scenario
You want to present multiple lines in an "alert" message in JavaScript. How do you have new lines with text in JavaScript?
Possible Solution #1 (less preferred)
Use syntax like this:
var y = `
line1
line2
line3
`;Possible Solution #2 (preferred)
var z = [
line1,
line2,
line3
].join("\n");You could use this stand-alone file multiline.html:
<!DOCTYPE html>
<html>
<body>
<h2>This demonstrates a multi-line variable in JavaScript</h2>
<p id="demo"></p>
<script>
line1 = "aaa"
line2 = "bbb"
line3 = "ccc"
var z = [
line1,
line2,
line3
].join("\n");
alert(z)
</script>
</body>
</html>
