How do I make a global variable using local variables?

Question

I am making a new video game and I need help with a purchase feature. I want to use local variables to "create" a global variable. For example:

function example(apple,banana) {
    return unicorn.apple.banana.text
}
example(taco,burrito);

should return whatever unicorn.taco.burrito.text equals.

Answer 1

For this you need to use the Array Notation.

function example(apple, banana) {
    return unicorn[apple][banana].text
}
example(taco, burrito);

Because you need to replace apple and banana, with their values.
