Is it still necessary to import isNill from lodash.isNill instad of import {isNil} from lodash?

[seyyedhassanpour]

why we need to use

import groupBy from 'lodash.groupby'  
import isNil from 'lodash.isnil'

instead of below?

import {groupBy,isNil} from 'lodash'

is this still needed?

There are a bunch of different approaches and results and most of the are for 2020, 2019 or older.
What is the rightway? can we use a syntax like this

import {groupBy,isNil} from 'lodash' or 'lodash-es'

And what is the difference between the lodashandlodash-es`?
It would greatly appreciated it if anyone shed some light on this topic.

For modern environments you should import from lodash-es.

import { groupBy } from 'lodash-es'

Thank you for your response. It would be greatly appreciated if you answer this one:
With this pattern, all the package wont be included into final bundle?

Assuming that none of your other dependencies rely on the base 'lodash' package, that's correct. If they do, however, you will likely get double lodash included.

import groupBy from 'lodash/groupBy'

What will happen if I use it like this?🧐

Then you'll get double groupBy if you have the full lodash imported anywhere already... Triple if you also have lodash-es, and quadruple if you also have lodash.groupBy... etc... 😢

There are so many different way to accidentally end up with multiple lodash packages installed.
