SameValueZerois the algorithm of how to compare two values in lodash. It’s similar to JavaScript “strict equality comparison” (===), except the handling ofNaN. It always makes developers confused asNaN === NaNreturnsfalse.SameValueZeroremoves that confusion, soNaNis the same toNaNinSameValue...
To truly understand the benefits of es-toolkit, let’s compare its performance and bundle size to Lodash. Performance es-toolkit’s functions are often faster than Lodash’s because they use modern JavaScript APIs in their implementations. For example, es-toolkit’somitfunction is about 11.8 times...
