declare a simple function in Javascript

  function simpleFunction(param1, param2) {
    // code to be executed
  }

This code declares a simple function called ‘simpleFunction’. It takes two parameters, ‘param1’ and ‘param2’. The code to be executed by the function is enclosed within the curly braces { }, which follows the parameter definitions.By assigning this code to a function, it can be called multiple times, rather than having to retype and execute the code repeatedly. This code serves as a template and can be modified with different parameters or code to be executed.
