Function parameters in JavaScript

Functions can take data as parameters. For example, let's make a function that will take a number as a parameter:

function func(num) { }

Let's make the function square the passed number:

function func(num) { console.log(num ** 2); }

Let's test the function by calling it with different numbers:

func(2); // shows 4 func(3); // shows 9

Make a function that takes a number as a parameter and prints the cube of this number to the console.

Make a function that takes a number as a parameter and checks if the number is positive or negative. In the first case, let the function output the text '+++' to the console, and in the second case, '---'.
