Function: addedLines()

addedLines(before, after): object[]

What an add put in the basket: each line of after whose quantity grew since before, with the quantity it grew by — what an AddToCart event reports, never the whole basket. Empty when nothing went in, as when the basket was full.

Code
const before = basket.getLines();
const added = addedLines(before, basket.addSelections(line, selections));
if (added.length === 0) showBasketFull();
else tracker.track("AddToCart", buildMetaAddToCartPayload(added));

Parameters

before

readonly object[]

after

Returns

object[]
