const percentFormatter = new Intl.NumberFormat('en-US', {

const s = percentFormatter.format(x);Uses an Intl.NumberFormat to create a human-readable percentage string.
const s = Math.round (x * 1000) / 10 + '%'Sadly there's no builtin in JavaScript for this sort of thing.

s = '{:.1%}'.format(x).1 means only one digit after decimal point.
% handles the "multiplication" and shows the percentage sign.
% handles the "multiplication" and shows the percentage sign.
s = '%.1f%%' % (x * 100)s = format(x, '.1%')s = f"{x:.01%}"
