How can I assign a javascript variable in html format?

For example, there is a page like below.

<html>
<head>
<title>Variables!!!</title>
<script type="text/javascript">
var lookatthis = 11;
var one = 22;
var two = 3;
var add = one + two;
var minus = one - two;
var multiply = one * two;
var divide = one/two;
    document.write("First No: = " + one + "<br />Second No: = " + two + " <br />");
    document.write(one + " + " + two + " = " + add + "<br/>");
    document.write(one + " - " + two + " = " + minus + "<br/>");
    document.write(one + " * " + two + " = " + multiply + "<br/>");
    document.write(one + " / " + two + " = " + divide + "<br/>");
</script>
</head>
<body>
</body>
</html>

I want to assign the javascript variable "lookatthis" on debug console.

//apologise for my ambiguous question. I would rather say, "I want to assign new value to variable "lookatthis" on this web-page using console on explorer."

Thank you for your kind teaching.)

If what you want is to be able to 'set' the value of lookatthis, you can use an input and using jquery or pure js get the value of the input and assign it to 'lookatthis'.

Edit: You can also use in the chrome console: lookatthis=25 but as your script loads when page loads, changes will not be shown but the value will be changed

You achieve it by using prompt function 

var lookatthis = prompt('Type the lokaltthis value');

Open debug console and write there:

lookatthis = 20

Anywhere in your script block after your initial assignment of lookatthis, you can write the value to the console with the command:

console.log(lookatthis);

You can use the log method:

console.log(lookatthis);
