In Array.prototype.flatMap, Javascript performs the .map before the .flat .
This means that the result of
var array = [1, 23, [10, 43]]; console.log(array.flatMap(item => item + 2));
Should be [3, 25, "10,432"] instead of [3, 25, 12, 45]
[3, 25, "10,432"]
[3, 25, 12, 45]
as
is equivalent to
var array = [1, 23, [10, 43]]; console.log(array.map(item => item + 2).flat(1));
