JAVASCRIPT ALERT FUNCTION

The alert function, alert(), is an in-built javascript function that allows for the displaying of an alert message.

Takes a string or combination of string and variables to output as it's argument and outputs them accordingly.

Example: String Only

<script type="text/javascript">

alert("This is Bond, James Bond");

</script>

The above will alert a message of: This is Bond, James Bond

Example: String And Variable Combined

<script type="text/javascript">

var name ="James";
alert("Hello " + name);

</script>

The above will alert a message of: Hello James. Note that strings and variables are separated by the concatenation operator +. Also note that in the alert statement, strings have double (can be single) quotation marks whilst variables do not.
