Tests:

reduce
values.reduce((prev, status) => prev + +(status === 'dupa'), 0)
filter
values.filter(status => status === 'dupa').length
for
var c = 0; for(var i = 0; i < values.length; ++i) { c += +(values[i] === 'dupa'); }
forin
var c = 0; for(var v in values) { c += +(v === 'dupa'); }
ternary
var c = 0; for(var i = 0; i < values.length; ++i) { c += values[i] === 'dupa' ? 1 : 0; }
