Javascript and Variables

JavaScript Variables

Like many other programming languages, JavaScript has variables. You can place data into named variables and then refer to the data simply by referring to the name of the variable.

Before you use a variable in a JavaScript program, you must declare it. Variables are declared with the var keyword as follows.

<!--

var money;

var name;

//-->

</script>

You can also declare multiple variables with the same var keyword as follows −

<!--

var money, name;

//-->

</script>
