To create a new Function Calculator from an existing JavaScript function definition.

From MDN:

A function definition (also called a function declaration, or function statement) consists of the function keyword, followed by:

• The name of the function.
• A list of parameters to the function, enclosed in parentheses and separated by commas.
• The JavaScript statements that define the function, enclosed in curly brackets, { }.

For example, the following code defines a simple function named square:

function square(number) {
   return number * number; 
}

CALC 1 Function Calculators require that the parameters and the return value be a Number. (An integer or floating point number. For example: 42 or 3.14159.)

1. Copy the function to the clipboard.
2. Tap the "Edit" button, then the add (+) button.
3. A new Function Calculator is created and is ready to use.
4. Use the Function Calculator Editor to edit the parameter and test the body of the function.

You will want to add the hints and optionally the key labels for the parameters.
