New page

Variables are used in programming to hold values. In JavaScript you make a variable with <tt>var</tt>.
<edcode>
var x;
print("the value of x is:"+x);
</edcode>

Putting a value into a variable is easy, just use <tt>=</tt>.
<edcode>
var p;
p=153;
print("the value of p is:"+p);
</edcode>

You can make a variable and give it a value all in one line
<edcode>
var variableName=721;
print("the value of variableName is:"+variableName);
</edcode>

Using JavaScript, you can place any value into a variable,
<edcode>
var w;
w="octopus";
print("the value of p is:"+w);
</edcode>

When I said "any value" I really meant it. Watch this one.
<edcode>
var z;
z=print;
z("the value of z is:"+z);
</edcode>

 Because variable can change value you can use them to hold information about what the program is doing right now.
