All kidding aside, a lot of our lodash code ends up looking something like this:
function (xs) {
return _(xs).pluck('foo').filter().value();
}
That code clearly expects that xs is an array of objects. However, we might occasionally end up with xs being undefined, or with xs being an array but one of the elements is null, etc.Most of the time, we want our function to just swallow those errors and return an empty array in such cases. This is exactly what lodash does, but if we tried to call xs.map(...) in that case we'd get an error. Similar caveats apply for grabbing the foo attribute if one of the array elements ends up being null or something.
For this reason, I recommend continuing to use lodash almost all of the time, even when there's a native Javascript method available.
