As an alternative to the first example I would propose Array.prototype.join(), i.e. remove the text variable and set the HTML to fruits.join(''). In well structured code scope and GC will clean up the fruits array when appropriate.
It's common to have use for both the old array and the new one, e.g. for time travel through app state or when both sets might get rendered depending on user input. When building complex applications one also tends to prefer to avoid data mutations to make code more readable and easier to debug, functional mapping tends to be appropriate for this purpose.
