Tests:

for
for (var i = 0; i < data.length; i++) { data[i]; }
foreach
data.forEach(function(i) { data[i]; });
for in
for (var i in data) { data[i]; }
for..of
const criticalityCount: Record<number, number> = {}; for (const [, criticality] of data) { if (criticality === 0) { continue; } if (criticality in criticalityCount) { criticalityCount[criticality]++; } else { criticalityCount[criticality] = 1; } }
