write me a simple javascript function

write me a simple javascript function Sure! Here's an example of how I can create and use JavaScript functions. This is quite basic, but it should give you a good starting point for understanding:

javascript 
     function add(a , b) {   //define the method/function with parameters 'name' and age.    return a +b; }

var x = add(5,3); //call the method by passing parameters (in this case we pass numbers) and assign it to variable 'x'.

javascript 
     console.log( x ); //print the result on your webpage/console using `document` object, this will print '8' to browser Console

This is a very simple function. In real world applications you would likely have more complex functions with parameters and return statements, but this should give an idea of how to create basic JavaScript methods/functions!
