Replace lodash with native API #3753
Description
Feature Request
The idea came from hexojs/site#1139 (comment) & #3677.
There is an article suggests we don't need lodash anymore.
According to benchmark below we can see es6 performance more or less as same as Lodash, in term of CPU, Memory or Handling time, at least in browser.

- https://www.reddit.com/r/javascript/comments/8j2hmq/performance_lodash_vs_es6_map/
There are also some benchmark of lodash vs es6 and es6 is definitely much faster in browser:

IMHO, we might consider replace at least some lodash with native js.
