js function or variable?

Question

JavaScript

Hi all.
which is preferable to a function or a variable, I am writing a react component, where the value should be displayed in the markup.
it can be evaluated as a function and called in markup
like

const getQuantity = () => {
        return products.length
    }

or as a variable
for example
const quantity = products.length

Damn question... Sorry! Is the length property the same for products? If yes, then it is const
