I$\text{'}$m trying to experiment with the map function using callback functions

Can you please show me how to: Create an array of numbers and assign it to a variable.

Create a named function that will take a single parameter, do a calculation on it $($sqrt$,$ sqr$,$ addition, etc$),$ and return the result. Then, Test your function with a few different numbers.

Use map on your array using your function as a callback to operate on all the numbers in your array. Now use a new anonymous function as a callback with map to do some new operation on each of the numbers in your array. Then, sett a variable to the results of your map function and print it out. Then transfer it to a JavaScript file. Put a comment block at the top of your program and add your working code from your condole experiment in your JS file. Use console.log$()$ or to print out your results in the console.

Please give me the code to do this, I could not figure it out last time I did it and want to see where I went wrong $($for practice and learning purposes!!! this is an old pr$0$ject$)$
