It is fast, It is nearly more than 2 or 20 times faster than immer in different situations. Click this online perf demo (https://codesandbox.io/s/limu-simple-perf-case-ycky1t?file=/...) to review the amazing result.
See more perf test result 1. git clone git@github.com:tnfe/limu.git 2. cd benchmark 3. npm i 4. node ./limu-vs-immer.js
You can change the params in limu-vs-immer.js file to test perf of different situations
const hasArr = false; // operate arr or not const lessDeepOp = true; // has more deep operation or not
