Array.from() takes a second argument which is a map. Example: Array.from(Array(10), (element, index) => //some logic to fill the array)

"localization" referred as "l10n", and "internationalization" referred as "i18n". cause,
l10n => "l" in between 10chars(o, c, a, l, i, z, a, t, i, o) and then "n"
i18n => "i" in between 18chars and then "n"
Also Globalization (g11n), Localizability (l12y).

in es6 you can now proxy your object's operation like get, set etc. All you need to do it create a proxy on a object like const proxyObj = new Proxy(initialObj, handler) the initial object is the object that you want to create proxy for and handler object is the place where you override object's method like get and set.
