This experiment is designed to find out the performance and resource usage of map functions of both and ES6 Lodash As the result of the _(2015)_shows that, Lodash performances faster than Native Javascript. I was shocked! Lodash is built on top of Native Javascript, how come a wrapped lib could do the same things faster than its mother language? article in jsperf.com For the reason of curiosity, an experiment is made, by handling 10000 objects array, on both method, to see the different of between them by time, CPU and RAM. Feel free to clone the . git 1- Generating a json file with 10,000 objects array $ node gen 2- Two Fighting Players es6 map vs lodash map speed 3- Kick off fighting Result As the table above shows, map() in performance more or less as same as Lodash, in term of CPU, Memory or Handling time. ES6 Update Thanks to correcting the experiment mistake, by and . Requiring module should have been considered.
