The simplest showBin (or showIntAtBase), using default digit characters, would use JavaScript's standard String.toString(base):
<lang JavaScript>
// showIntAtBase_ :: // Int -> Int -> String
[5, 50, 9000].map(function (n) {▼
const showIntAtBase_
// showBin :: Int -> String
)</lang>▼
const showBin = n => showIntAtBase_(2, n);
// GENERIC FUNCTIONS FOR TEST ---------------------------------------------
<pre>101▼
// intercalate :: String -> [a] -> String
110010▼
const intercalate = (s, xs) => xs.join(s);
10001100101000</pre>▼
// map :: (a -> b) -> [a] -> [b]
const map = (f, xs) => xs.map(f);
// unlines :: [String] -> String
const unlines = xs => xs.join('\n');
// show :: a -> String
const show = x => JSON.stringify(x);
// TEST -------------------------------------------------------------------
return unlines(map(
n => intercalate(' -> ', [show(n), showBin(n)]),
));
