Question 1

How to use Lodash with ES6 import syntax?

Accepted Answer

Install the `lodash-es` package for ES module compatibility, or use per-method imports from `lodash` with bundlers that support tree-shaking. The README mentions `lodash-es` and tools like babel-plugin-lodash for optimization in modern setups.

Question 2

Lodash vs Underscore: which is better?

Accepted Answer

Lodash is generally preferred for its larger feature set, better performance optimizations, and active maintenance under the OpenJS Foundation. Underscore is lighter but less comprehensive; choose Lodash for reliability in complex data manipulations.

Question 3

How to reduce Lodash bundle size in webpack?

Accepted Answer

Use the lodash-webpack-plugin to strip unused features and enable tree-shaking. Also, import specific methods or use `lodash-es` with ES modules, as noted in the README's module formats section.

Question 4

Is Lodash still necessary with modern JavaScript?

Accepted Answer

For legacy projects or complex data transformations, yes, due to its consistency and performance. However, for new projects, evaluate if native ES6+ methods suffice, as many Lodash functions are now redundant.

Question 5

How to use Lodash for functional programming?

Accepted Answer

Import the `lodash/fp` module to access auto-curried methods like `map` and `filter` with immutable data-last patterns. Refer to the FP Guide in the wiki for examples on composing functions effectively.

Question 6

Lodash or native methods for array manipulation?

Accepted Answer

Native methods are faster for simple cases and avoid dependencies. Use Lodash when you need cross-environment consistency, performance optimizations for large datasets, or handling edge cases that native methods miss.
