Looking at the documentation for ES6 Object.assign and Lodash _.assign it looks like these function in exactly the same way.
Is that a correct understanding? Or am I missing something?
回答1:
Depends on the browser. Per the lodash docs:
Made _.assign use built-in Object.assign when available.
You can go here for browser support:
Basically, IE doesn't have support so lodash's code is used in that case
