Math.max

const data = ["37.02","15.75","11.22","7.88","6.50","4.83","3.45","2.56","1.93","1.51","1.20","0.95","0.79","0.64","0.54","0.42","0.35","0.32","0.29","43.17"];
// (20) ["37.02", "15.75", "11.22", "7.88", "6.50", "4.83", "3.45", "2.56", "1.93", "1.51", "1.20", "0.95", "0.79", "0.64", "0.54", "0.42", "0.35", "0.32", "0.29", "43.17"]

Math.max(data.map(item => (Math.ceil(parseInt(item) / 10) * 10)));
// NaN
data.map(item => (Math.ceil(parseInt(item) / 10) * 10));
// (20) [40, 20, 20, 10, 10, 10, 10, 10, 10, 10, 10, 0, 0, 0, 0, 0, 0, 0, 0, 50]

Math.max(...data.map(item => (Math.ceil(parseInt(item) / 10) * 10)));
// 50

reduce

array & max & min

Array.prototype.max = function() {
  return Math.max.apply(null, this);
};

Array.prototype.min = function() {
  return Math.min.apply(null, this);
};
