I don't think the idea is "if you need these 6 simple functions, use lodash, not vanilla JS". If you only need 6 simple functions, then writing them in house makes sense. But suppose you already have usecases for lodash's more complex functions. It can make sense to use a library like lodash to fill in those functions rather than utilizing your own. And if you already have lodash available, you may as well use it for simple functions, too, rather than write your own.
