Strongly recommend trying [limu](
https://github.com/tnfe/limu)，it is now the fastest immutable data js lib，and it is also production environment available.
//You can verify through the following tests, and you are also welcome to add more performance test cases
```bash
git checkout https://github.com/tnfe/limu.git
cd benchmark
npm i
## Then execute the following commands separately
npm run s1
npm run s2
npm run s3
npm run s4
```
The results of one set of performance tests
At the same time, the number of single test cases has increased to 500+, with a coverage rate of '95+' (the results can be viewed by executing NPM run tests in the root directory)
