Benchmark Results

Method	Test	Performance Comparison	hidash ops/sec	lodash@4.17.21 ops/sec
isArray	src/isArray.bench.ts > isArray performance	hidash is 8.90x faster	516.84 🏆	58.05

Note: Higher operations per second (ops/sec) numbers are better. Each test compares hidash vs lodash implementation.

⚠️ indicates where hidash is slower than lodash.

🏆 indicates the faster implementation.

@yceffort-naver

I have a question since I couldn't see the merge button, I was wondering how I should go about merging. Could you let me know the proper way to do it?

[yceffort-naver]

Oh, sorry about that—I didn’t realize external contributors couldn’t see the merge button. I’ll go ahead and merge it myself. Thanks again! 😊

[umsungjun]

Yes, thank you as always 😊
