Performance Tips

Optimizing Lodash Usage

While Lodash is generally performant, there are ways to optimize its usage for better performance.

Use Native Methods When Possible

For simple operations, native JavaScript methods can be faster:

// Lodash
_.map([1, 2, 3], n => n * 2);

// Native (faster for simple operations)
[1, 2, 3].map(n => n * 2);

Cherry-pick Methods

Import only the methods you need to reduce bundle size:

import map from 'lodash/map';
import filter from 'lodash/filter';

Use _.flow() for Function Composition

_.flow() can be more efficient than chaining for certain operations:

const transform = _.flow(
  array => _.map(array, n => n * 2),
  array => _.filter(array, n => n > 5)
);

transform([1, 2, 3, 4]);
// => [6, 8]
