17. Replacing Characters in a String
JavaScript
<!DOCTYPE html>
<html>
<head>
<title>String
Replace</title>
</head>
<body>
<script>
var str = "Hello world!";
var newStr = str.replace("world",
"everyone");
document.write(newStr);
</script>
</body>
</html>
This replaces the word
"world" with "everyone" in the string.
