Since JavaScript commands run on the browser, we need to add JavaScript codes to our web page.
There are various methods of adding JavaScript code to a web page.
JavaScript codes can be written between the <script> and </script> tags.
<script>
alert("baransel.dev");
</script>
It can be written to HTML properties such as onclick, which indicates when the HTML element is clicked, onmouseover, which indicates that the HTML element is hovered.
<button onclick="alert('baransel.dev')">Click</button>
After the JavaScript codes are written to the external .js file, the <script> tag can be written to the src property by specifying the file name.
JavaScript codes (example.js)
alert("baransel.dev");
HTML Codes
<script src="example.js"></script>
Codes are written to the external JavaScript file without the
<script>and</script>tags.
Written JavaScript codes can be inserted into <head> or <body> tags.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Baransel Arslan</title>
</head>
<body>
<script>
alert("baransel.dev");
</script>
</body>
</html>
Long JavaScript commands can slow down the page load.
If the codes in the page or in external JavaScript files are added to the end of the
<body>tag, the page will open faster.
