JavaScript was initially created to "make web pages alive"
The programs in this language are called scripts.They can be written right in a web page's html and run automatically as the page loads.
A code editor is the place where programmers spend most of their time.There are two main types of code editors:IDE and lightweight editors.Many people use one tool of each type.
The script tag can be put inside html body tag or we can create JS file separately and add reference to it.
<script>
alert("Hello ,World");
</script>
When this script is executed it will show one pop up showing Hello ,World
Exercise : Now create a script in html that should show one pop up when the browser runs. NB:You can use Online IDE or Visual Studio Code to perform these exercise.
