How to use’chain’with’lodash-es’while supports tree shaking?
How to use `chain` with `lodash-es` while supports tree shaking? As we all know, lodash-es is built with a more modular syntax for supporting tree shaking by build tools. However, chain related features means some functions are attached to a object/prototype chain.
