Count dataLayer events by name
The button groups dataLayer entries by event name and prints a console table with the count of each one.
Code to copy
try {
var dl = window.dataLayer;
if (!Array.isArray(dl)) {
console.warn('No dataLayer array found on this page.');
} else {
var counts = {};
dl.forEach(function (item) {
var ev = (item && item.event) || '(no event)';
counts[ev] = (counts[ev] || 0) + 1;
});
console.log('dataLayer entries: ' + dl.length);
console.table(Object.keys(counts).map(function (ev) {
return { event: ev, count: counts[ev] };
}));
}
} catch (e) {
console.warn('dataLayer event count failed:', e);
