What are different ways to use the JavaScript?

 JavaScript can be used using three ways

• Immediate Script
• Code get executed automatically when  we load a web page
• Deferred Script
• Code get executed based on some event
• We need to create a function to link with some event attribute
• Use function keyword to define the functions in the JavaScript
•  Hybrid Script
• Some code get executed at the time of loading the page and other code get executed based on some event

Example of Immediate Script

<script>

//immediate script code

alert("Welcome to JavaScript");

</script>

Example of Deferred Script

<script>

function welcome(){

alert("OOPs! You Clicked");

}

</script>

<input type="button" value="Click Me" onClick="welcome()">

Example of Hybrid Script

<script>

alert("This is an example of Hybrid Script");

function welcome(){

alert("OOPs! You Clicked");

}

</script>

<input type="button" value="Click Me" onClick="welcome()">
