1) The right way todo conact arrays is array1.concat(array2). Plus does not mean concat in Javascript. In python this works withs lists. In Java this would also not work. Nothing strange in js.
2) Is correct and here it how the unary plus (+) works: developer.mozilla.org/en-US/docs/W.... Usually an error like this is shown by your editor :)
3) I would advise everybody to read the explination :)
4) This only happens in .html files if you try todo that in .js files you will get an error
5) Really nothing special to JS in Java for example MIN_VALUE float is 2-149. Just how signed float(numbers) in computer science usually work.
