#12 JavaScript Introduction

What is JavaScript?

How do we usually write JavaScript language?

Example

<script type="text/javascript">
    alert("Always call your girlfriend 'young lady' means...");
    alert("You are good at safing your relationship.");
</script>
  • Add a tag <script></script> and an attribute to indicate that the language we’re writing is JavaScript.
  • A command, alert, and its string "Always call your girlfriend 'young lady' means..."
    • The string can be multiple, but don’t forget to add a semicolon in the end of it.
