False positive for chainable on minBy

[corbinu]

I am getting a false positive for chainable

I am starting with an array like this:

let test = [
    {
        "name": "a",
        "age": 18
    },
    {
        "name": "b",
        "age": 21
    },
    {
        "name": "a",
        "age": 55
    }
];

I want to convert this to the min age for each name
Correct end result is

[{"name": "a", "age": 18},{"name": "b", "age": 21}]

I am trying this:

testResult = _(test)
    .groupBy("name") // {"a": [{"name": "a", "age": 18}, {"name": "a", "age": 55}], "b": [{"name": "b", "age": 21}]}
    .map((sameName) => _.minBy(sameName, "age")) // [{"name": "a", "age": 18}, {"name": "b", "age": 21}]
    .value();

OR

let groupedNames = _.groupBy(test, "name");
testResult = _.map(groupedNames, (sameName) => _.minBy(sameName, "age"));

I am not sure why I get an error on both of these of "refer lodash chain (lodash/prefer-lodash-chain)"
This seems to be incorrect as minBy is not chainable

Perhaps there is a better way though?

Hi,
This is generally what I would do for this problem (either is fine, though I prefer chaining, since it doesn't require creating intermediate variables).
This looks like it really is a false positive, we'll look into it.
