es-toolkit, a Lodash alternative

Comparison between es-toolkit and Lodash

• Functionality: es-toolkit offers key utility functions similar to Lodash, covering areas like functions, arrays, objects, strings, math, predicates, and promises.
• Performance: es-toolkit functions are often faster and have smaller bundle sizes compared to Lodash equivalents, due to their modern JavaScript implementations and TypeScript support.
• Interdependencies: es-toolkit functions are mostly standalone, preventing unintended inclusion of unnecessary code, unlike Lodash where utility functions are often interdependent.

Key features of es-toolkit

• Functions: Cache results, limit function calls, handle arrays, objects, strings, math, predicates, promises, and more.
• Arrays: Filter out duplicates, find differences between arrays.
• Objects: Deep clone, transform nested objects to a flat structure.
• Strings: Convert to kebab-case.
• Math: Generate and round random numbers.
• Type guard functions: Easily check for null or undefined values.
• Asynchronous utilities: Pause execution.

Performance and bundle size comparison

• es-toolkit's throttle function is about 11.8 times faster than Lodash's equivalent.
• es-toolkit functions have smaller bundle sizes and better load times compared to Lodash.
• Using es-toolkit's functions can improve performance and optimize bundle size.

Pick example

• es-toolkit's pick function is useful for extracting specific properties from an object, improving code readability and maintainability.

Conclusion

• es-toolkit is a high-performance, lightweight alternative to Lodash, offering faster functions, smaller bundle sizes, and better optimization for JavaScript projects.
